I'm not sure if this is the best approach, or if changing
too_many_packs can be done without causing problems for
hosts of big repos.

Subject: [PATCH] gc: correct gc.autoPackLimit documentation
I want to ensure there is only one pack in my repo to take
advantage of pack bitmaps. Based on my reading of the
documentation, I configured gc.autoPackLimit=1 which led to
"gc --auto" constantly trying to repack on every invocation.
Update the documentation to reflect what is probably a
long-standing off-by-one bug in builtin/gc.c::too_many_packs:
- return gc_auto_pack_limit <= cnt;
+ return gc_auto_pack_limit < cnt;
However, changing gc itself at this time may cause problems
for people who are already using gc.autoPackLimit=2 and
expect bitmaps to work for them.
