Subject: wildmatch: replace variable 'special' with better named ones
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=b6a3d3353f799c8c5afedb2da4df6e7cdc5d00c9;p=git.git

wildmatch: replace variable 'special' with better named ones

'special' is too generic and is used for two different purposes.
Replace it with 'match_slash' to indicate "**" pattern and 'negated'
for "[!...]" and "[^...]".
