[mapserver-dev] 6.4 stable branch gone wild

[thomas bonfort]

Even, a checkout at b7cb5712b6bcd which is right before that postgis
pull request, contains fontcache.c , i.e. already has master merged.
Daniel, I don't think this happened through the github interface, but
rather through the git command line (Steve, please confirm). My guess
is that there was a "git merge 75f548e77" instead of a "git
cherry-pick 75f548e77" run on the 6.4 branch (75f548e77 at that time
was master plus 1 commit)
