The call to FcStrSetMember in FcCacheReadDirs is unneeded (here and
elsewhere), because FcStrSetAdd calls _FcStrSetAppend, which starts with:
if (FcStrSetMember (set, s))
Also it would be good to avoid having this difficult-to-understand
global processed_dirs variable. I'd much rather have it be passed to
FcCacheReadDirs. Once I review Takashi's first patch (hopefully later
today) I'll commit a modified version of this patch.
