Add feedback-patches, a script to ... feedback patches:
The feedback-patches script is intended to help sending back patches in
the NetBSD Packages Collection, pkgsrc, back to the maintainers of the
original package, for inclusion into future releases. The given
category/pkg is either a path relative to the pkgsrc base directory, or
an absolute patch, which will be stripped the base directory. A pathname
of . will be expanded to the current directory, which is useful when the
current working directory is in a package's directory in pkgsrc.
If an email address is given, the patches will be sent to that address,
with some nice words. If no email address is given, the mail will only be
displayed instead of sent.
See feedback-patches(1) for the full enchilada.
