Subject: do not segfault on empty filename to escape.
X-Git-Tag: submit/efl/20131021.015651~9394
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b5d5b3378c959de9190be393e8af87bae7d98344;p=platform%2Fupstream%2Fenlightenment.git

do not segfault on empty filename to escape.

Avoid case where e_exec (and possible others) gives
e_util_filename_escape() a NULL parameter, actually another bug, but
does not hurt to safe guard this one.
