Subject: files: Return nothing if there are no files
Patch-mainline: yes
Git-commit: 4d8358ae52ce574920c7f3aba7453f305fabf1ba
References: bnc#872719

"quilt files" returns a blank line if no files are included in the
patch. This could easily break constructs such as "quilt files | wc
-l". Let "quilt files" return nothing at all if there are no files in
the patch.
