Bug#872432: licensecheck: option to add additional "ignore" patterns

[IOhannes m zmoelnig]

Package: licensecheck
Version: 3.0.30-1
Severity: wishlist

Dear Maintainer,

licensecheck comes with an '--ignore' option that allows to specify a filename
exclusion pattern.
unfortunately, using that option will *override* the built-in ignore patterns,
which are (not very) accurately defined in the help with "some backup and VCS
files".
in most cases, i would like to specify additional ignore patterns, without
having to worry about what "some backup and VCS files" really means and without
having to maintain these files seprately, thus duplicating the work of the
licensecheck upstream.
fwiw, usually i'd like to ignore some binary files.

i therefore would like to suggest to add an(other ?) option that would allow me
to specify an *additional* filename pattern to be ignored.
