The patch didn't fully translate from the rpm git repo to the debugedit
repo, but I figured out how to apply it anyway. I added a "dwz (1)" to
the documentation for -m.

It seems a useful option, so I pushed it.

I think if you do/set this then you can simply not create the .dwz
directory (which would later be removed because empty) and you could in
theory run the dwz instances in parallel with separate dwz invocations.

But note that find-debuginfo.sh isn't fully integrated yet into
debugedit. It still contains various dependencies on rpm, see 
https://sourceware.org/bugzilla/show_bug.cgi?id=27637 it doesn't have
proper --usage/help support and it doesn't have a testsuite yet.

Cheers,

Mark
