Subject: Properly detect if given a directory name as argument.
X-Git-Tag: 0.04~30

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).
