Subject: Trims slashes from the argument to rmdir(), likewise
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=0c54f65beca99cd47fc978febc1180b492e468de;p=p5sagit%2Fp5-mst-13.2.git

Trims slashes from the argument to rmdir(), likewise
to what happens with rmdir(). Factorize the code in a
local macro, TRIMSLASHES.
