Patch 4 has the meat of this series.
While running valgrind to check that I didn't leak any memory, a couple
of leaks were spotted. Patches 1-3 address them.
Major change in v2: implement Thomas' idea  about using
help.autocorrect to configure this behaviour.
Jeff King (1):
help.c::uniq: plug a leak
Tay Ray Chuan (3):
help.c::exclude_cmds: realloc() before copy, plug a leak
help.c: plug leaks with(out) help.autocorrect
allow recovery from command name typos
