Remove empty directories only if they match exclude pattern.

[r4um]

Current exclude logic even removes the directories left empty after "exclude match" but which
don't match the exclude pattern.

This for example makes empty directories maintained under subversion
to be excluded (via --exclude '**.svn*') even though intention is to include them.

[r4um]

spec fails though --exclude dirpath via fpm command doesn't work.

Looks like an internal check, working on fixing so it passes the spec.

[r4um]

I shouldn't be deleting example as per my change, something on following lines doesn't delete example

if File.fnmatch(pattern, d) or File.dirname(file_staging_path) == "#{d}"
   #delete dir

But again breaks the spec as user wanted to delete example/foo not example. Thoughts ?

[jordansissel]

Spec can be changed. I'm most interested in fpm behaving in "the most obvious manner by default"

How about writing up the spec changes as well?

[r4um]

Thanks, I'll work on the code/spec.

[r4um]

The changes are now complete.

• Use the ruby Find module, this allows to match against all possible paths.
• Use File.fnmatch only, since File.fnmatch('example/foo, 'example/foo') is true.
