The code to find a suitable sanctuary location is flawed: to find
space and resources around the location, it does a depth-first search
limited to 300 sectors. Pretty useless when the limit is reached. A
breadth-first search would work, but why bother? This feature is
obscure and rarely (if ever) used: no conscientious deity would use it
for a real game, and for blitzes fairland does a better job. Remove
it.
Where ordinary selectors specify a value stored in some object,
virtual selectors specify a function to call to compute a value
associated with some object.
Use them to replace the special case xdump ver by new table
EF_VERSION.
Move configkeys[] to lib/common because nsc_init() needs it to
initialize empfile[EF_VERSION].cadef.
Before 4.0.6, depth charges required no guns, one military, did damage
like shell fire from two guns, and used two shells. Missions were not
quite consistent with that (bug). 4.0.6 changed depth charges to work
exactly like shell fire (but without updating documentation
accordingly): require guns and gun crew, non-zero firing range, scale
damage and ammunition use with guns.
Go back to the old model, but with damage like three guns, to avoid
changing the stock game's dd now (three gun damage for two shells).
Stock game's af changes from two gun damage for one shell, and nas
from four gun damage for two shells.
Factor out common depth-charging code into shp_dchrg().
Always charge land units at least as much mobility for assaulting from
non-landing ships as for landing ships. Before, marines lost all
mobility when assaulting from a non-landing ship, which could be less
than what the same assault costs from a landing ship (half an update's
worth).
Detect .git instead of CVS. Use git-ls-files with git, else
$(srcdir)/sources.mk. info/findsubj.pl now gets the info files as
arguments rather than from sources.mk.
Remaking info subjects doesn't quite work, but it was broken similarly
before.
off-shore drilling like automatic fishing. Fix the formatting to be
more consistent with other info pages.
Add see also reference for Autofish to Autonav.
