[Quilt-dev] [PATCH] files: Return nothing if there are no files

[Jean Delvare]

"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" or "if [ -z "$(quilt files)" ]". Let "quilt files" return nothing
at all if there are no files in the patch.
