Subject: fix-shebangs: fix regression for symlinked files
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=0b4156a55f460d501145936fe7d1dec022f5a5f9;p=portage.git

fix-shebangs: fix regression for symlinked files

The code to check whether symlinked files point outside the prefix was
incorrect.  It didn't include the install image location, hence it
always concluded a symlinked script was pointing to outside the prefix,
leading to bugs like #378515.
