Revision 251df09be3af658404f5f5f670a013d5806645d4 authored by Matthieu Moy on 09 March 2011, 20:52:15 UTC, committed by Junio C Hamano on 09 March 2011, 22:28:24 UTC 
log: fix --max-count when used together with -S or -G
 
The --max-count limit is implemented by counting revisions in
get_revision(), but the -S and -G take effect later when running diff.
Hence "--max-count=10 -Sfoo" meant "examine the 10 first revisions, and
out of them, show only those changing the occurences of foo", not "show 10
revisions changing the occurences of foo".

In case the commit isn't actually shown, cancel the decrement of
max_count.
