Subject: fix glob failure to match plain "/" to root directory
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=84eff797e3e38210cc311b000b1586b948b4fc35;p=musl

fix glob failure to match plain "/" to root directory

the check to prevent matching empty string wrongly blocked matching
of "/" due to checking emptiness after stripping leading slashes
rather than checking the full original argument string.

simplified from patch by Julien Ramseier.
