From 251df09be3af658404f5f5f670a013d5806645d4 Mon Sep 17 00:00:00 2001 From: Matthieu Moy Date: Wed, 9 Mar 2011 21:52:15 +0100 Subject: [PATCH] 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.
