This is what I have done with this patch

Added editloc to change the description of the closest location
Added delloc to remove closest location
Added dumploc to place locs in memory into a .loc file (required for
editloc and delloc)
Added zdumploc to place locs in memory into a .loc.gz file (requred for
markloc, editloc and delloc)
Added loc.gz saving support to markloc, editloc and delloc (via
zdumploc)

Altered locs_load to use _Com_FOpenFile instead of Com_FOpenFile
Fixed potentual bug in locs_markloc
Fixed bug in Team_ParseSay that cause wierd behaviour if $ or % was last
charactor in line.

patch created from a development tree via diff -ur ../newtree ./
newtree and development tree were up-to-date at time of creating the
patch


Please let me know what you change so I may learn from it
