[PATCH v2 5/5] checkpatch: ignore a file named b

[Robert Elliott]

If a file named "b" happens to exist, checkpatch complains
as it parses the patch lines specifying the filenames.

	WARNING: patch prefix 'b' exists, appears to be a -p0 patch

Squelch that by only complaining if that is a directory,
not a regular file, and print the whole path causing concern.
	WARNING: patch prefix './b' exists, appears to be a -p0 patch
