Subject: Properly detect if given a directory name as argument.
X-Git-Tag: 0.04~30
X-Git-Url: https://ruderich.org/simon/gitweb/?p=blhc%2Fblhc.git;a=commitdiff_plain;h=23189f94e3761d3ef1d82b5abccf11564388b4bf;hp=2a259b08620582db1693281cded2deb29708e16b

Properly detect if given a directory name as argument.

Currently running blhc with a directory name as argument results in no
error except it warning there are no compiler commands in it. So check
if it is a proper file (or a link to a proper file).
