Also, some revision-limiting options can reduce the count like
git log --grep whatever
OK, --grep seems to work, but -S and -G do not:
$ ./bin-wrappers/git log -Sfoo --count
40012
$ ./bin-wrappers/git log -Sfoo --oneline | wc -l
925
$ ./bin-wrappers/git log --count
40012
See 251df09 (log: fix --max-count when used together with -S or -G,
2011-03-09) for a start of an explanation.
If implementing a proper count is too hard, one option is to forbid
--count -S and --count -G to avoid confusion.
