load_plane_ship() and load_plane_land() duplicate code to check
whether a plane can be loaded, except for the phrasing of one message.
Factor out into plane_loadable(). tran_plane() has equivalent code,
but wants different messages, which makes de-duplication unattractive.

load and unload silently skip unowned sectors, unlike lload and
lunload. Probably goes back to Chainsaw option ALLYHARBOR.
Drop that. Deities can now load and unload in unowned harbors and
canals. Mortals are now notified they can't.

These commands suppress some error messages when ships, planes or land
units involved aren't explicitly selected by UID. Without this, a
command like "unload plane 80 *" would complain about every plane not
on ship#80.
Correct a few issues with this error suppression:
1. We don't suppress the error when we can't load/unload a ship or
land unit because it's on the trading block. Do suppress it.
2. We suppress the error message when we can't load/unload due to
foreign sector ownership in all but one places. Fix that place.
3. Messages about explicitly selected planes and land units to load
are still suppressed when the carrier isn't selected explicitly.
Change this to suppress regardless of the carrier.
3. We suppress the error when a carrier has no room. Don't, because
it's a potentially confusing silent failure.

Attempting to unload land units from a carrier that can't carry any
prompts for land units to unload, while attempting to unload planes or
load land units or planes fails without prompting.
Fix this inconsistency by making unload and lunload fail early for
land units, just like they do for planes.

load and lload skip foreign ships unless explicitly named, and
suppress some error messages for ships not explicitly named. Makes
sense, except the check for "explicitly named" is flawed: it checks
whether the argument starts with a digit. Works as intended for lists
like 1/2/3. Broken for areas that happen to start with a digit, such
as 0:9,0:5. Visible in the load-tend test.
Screwed up when the feature was added in Empire 2.
Fix the obvious way: test for NS_LIST instead. While there, drop the
p && *p guard, because it's always true after snxtitem().

Unlike tend, ltend does nothing silently when asked to tend zero
commodities. This may leave the player guessing why the command did
nothing. Report the reason and fail the command, just like tend does.
While there, improve the prompt to match tend's.

Tending to a dead ship destroys, and tending from a dead ship revives.
Has always been that way. Not actually a problem for ltend anymore,
because the dead can't carry or be carried since commit 64a53c90f0,

Report the exact ship, like

instead of reporting just the ship type, like

Transferring commodities from tenders to targets continues with the
next tender when a target can't hold this kind of commodity.

there, because you can tend to foreign target ships as long as they're

Land units not on the tender are silently ignored. This may leave the
player guessing why the command did nothing. Reporting them all would
be annoying; I just changed tend to report only explicitly named ones.
Make ltend behave the same.
This does add a related annoyance: ltend can complain "not on ship"
when tending explicitly selected land units from multiple ships.

The quickest way to tend all land units on a ship is to select all
land units with '*'. However, tend then prints a "not on ship"
message for every land unit not on the tender, as the load-tend test
demonstrates. Annoying. Suppress this message unless the land unit
was explictly selected by UID. Similar to how load and unload
suppress messages, only they get the condition wrong (to be fixed
soon).
A related annoyance remains, also visible in the load-tend test: tend
can still complain "not on ship" many times when tending explicitly
selected land units from multiple ships.

Each land unit is tended to each target ship in turn, and ends up on
the last one that can take it.. The load-tend test demonstrates this
with command "tend land 173 s 150/165":
spy infiltrator #320 transferred from sbc cargo submarine (#173) to cs cargo ship (#150)
spy infiltrator #320 transferred from sbc cargo submarine (#173) to ls landing ship (#165)
spy infiltrator #321 is not on sbc cargo submarine (#173)!
spy infiltrator #322 transferred from sbc cargo submarine (#173) to cs cargo ship (#150)
spy infiltrator #322 transferred from sbc cargo submarine (#173) to ls landing ship (#165)
Has been that way ever since Empire 2 added tending of land units.
Fix by breaking tend_land()'s loop over all target ships after a
successful transfer.

Exercise load, unload, lload, lunload, tend, and ltend.
Notable coverage gaps:
* Effect on land unit fortification
* Effect on mission and retreat orders
* Ships, land units and planes on sale (option MARKET 1)
* Transmission of plague (option NO_PLAGUE 0)
* Land units loading and unloading civilians (need a custom land unit
type capable of carrying civilians)
* load refusing to load x-light planes (need a custom ship type that
can carry helo but not x-light)
* load and lload refusing to load land units carrying land units, and
lload refusing to load land units onto land units that are being
carried (need a custom non-heavy land unit type that can carry land
units)
* tend refusing to tend non-light land units to non-supply ships, or
to supply ships without room (need custom a non-light assault land
unit type)
This test exposes bugs. They're marked "BUG:" in the test input.
There are also oddities marked "odd:", and usability issues marked
"usability:".
