TREATIES has issues:
* Treaties can cover attack, assault, paradrop, board, lboard, fire,
build (s|p|l|n) and enlist, but not bomb, launch, torpedo and
enlistment centers.
* Usability is very poor. While a treaty is in effect, every player
action that violates a treaty condition triggers a prompt like this:
This action is in contravention of treaty #0 (with Curmudgeon)
Do you wish to go ahead anyway? [yn]
If you decline, the action is not executed. If you accept, it is.
In both cases, your decision is reported in the news.
You cannot get rid of these prompts until the treaty expires.
* Virtually nobody uses them.
* Virtually unused code is buggy code. There is at least one race
condition: multifire() reads the firing sector, ship or land unit
before the treaty prompt, and writes it back after, triggering a
generation oops. Any updates made by other threads while trechk()
waits for input are wiped out, triggering a seqno mismatch oops.
* The treaty prompts could confuse smart clients that aren't prepared
for them. WinACE isn't, but is reported to work anyway at least
common usage. Ron Koenderink (the WinACE maintainer) suspects there
could be a few situations where it will fail.
This feature is not earning its keep. Remove it. Drop command
treaty, consider treaty, offer treaty, xdump treaty, reject treaties.
Output of accept changed, obviously.

Spy units are now enabled when a land unit type with capability spy
exists. To disable them, deities have to customize table land-chr.
Before, spy units types were ignored when option LANDSPIES was
disabled. Except for xdump land-chr, which happily dumped unusable
spy unit types.
Trade ships are now enabled when a ship type with capability trade
exists. No such type exists by default; to enable trade ships,
deities have to customize table ship-chr.
Before, trade ship types were ignored when option TRADESHIPS was
disabled. Except for xdump ship-chr, which happily dumped unusable
trade ship types.
SLOW_WAR has issues:
* The check whether the attacker old-owns the attacked sector is
broken, because att_abort() uses sect.sct_oldown uninitialized.
Spotted by the Clang Static Analyzer.
* Its implementation in setrel() is somewhat scary. It's actually
okay, because that part of setrel() only runs within decl(). Other
callers don't reach it: update_main() because player->god != 0
there, and the rest because they never pass a rel < HOSTILE.
* Documentation is a bit vague.
SLOW_WAR hasn't been used in a public game in years. Fixing it is not
worth it, so remove it instead.
The abstract idea of tying ships and land units to a logistical tether
is sound, the concrete implementation as option FUEL is flawed. It
adds too much busy-work to the game to be enjoyable. It hasn't been
enabled in a public game for years. The code implementing it is ugly,
repetitive, and a burden to maintain.
Remove selector fuel from ship_ca[] and land_ca[], and selectors
fuelc, fuelu from mchr_ca[] and lchr_ca[]. Remove fields fuelc, fuelu
from ship.config and land.config.
Remove command fuel from player_coms[].
Deprecate edit key 'B' in doship(), dounit(), and don't show it in
pr_ship(), pr_land().
Drop opt_FUEL code from build_ship(), shi(), sdump(), ship_damage(),
show_ship_stats(), do_mob_ship(), nav_ship(), build_land(), land(),
ldump(), land_damage(), show_land_stats(), do_mob_land(),
resupply_all(), resupply_commod(), get_minimum(), has_supply(),
unit_list(), vers().
Remove opt_FUEL, fuel_mult, struct shpstr member shp_fuel, struct
mchrstr members m_fuelc and m_fuelu, M_OILER, struct lndstr member
lnd_fuel, struct lchrstr members l_fuelc and l_fuelu, fuel(), and
auto_fuel_ship().
(show): New sub-command.
(player_coms): Update its c_form.
(show_updates, fmttime2822): New.
(vers): Show game_days and game_hours.
(upda): Mark obsolete and point to show updates.
(vers): Point to show rather than update.
Rewrite much of info zdone.
(all): Depend on info.
Flatten info directory. This undoes the move to one subdirectory per
chapter, which was done during Empire 2. The structure doesn't buy us
much, as the info name space is flat, and it complicates makefiles.
Overhaul info.pl:
- It now wants to run in the root of the build tree.
- Information on source files and subjects is now stored in makefiles,
thus info.pl no longer picks up random junk from the file system.
- Clean up Perl anachronisms, in particular use subroutine arguments and
results rather than global variables where convenient.
- Change format of diagnostics to the common format used by GNU tools,
so that Emacs and the like can parse it.
- Catch missing .SA.
- When creating a new subject file, cowardly refuse to overwrite an
existing file.
- Subject files contain topics sorted by chapter, then by name. The
order of chapters used to depend on how Perl sorts hash keys. Fix
it.
