Bug#867302: licensecheck: incorrectly parses multi-line copyright notices

[Ximin Luo]

Package: licensecheck
Version: 3.0.29-1
Severity: normal

Dear Maintainer,

For https://sources.debian.net/src/sagemath/7.6-2/sage/src/sage/misc/edit_module.py/

$ licensecheck --copyright src/sage/misc/edit_module.py 
src/sage/misc/edit_module.py: GPL
  [Copyright: 2007 Nils Bruin <nbruin at sfu.ca> and]

This is wrong, but I can work around it with the following sed script:

$ cat src/sage/misc/edit_module.py | tr '\n' '\t' | sed -e 's/\(,\|\band\)\s*\t#\?\s*/\1 /g' | tr '\t' '\n' > fixed.py
$ licensecheck --copyright fixed.py 
fixed.py: GPL
  [Copyright: 2007 Nils Bruin <nbruin at sfu.ca> and William Stein <wstein at math.ucsd.edu>]

It would be good if this logic were incorporated into licensecheck itself. I'd
help, but my perl is really bad.

(Also perhaps the # in the regex should be a (?:#|//|/*) or something like that)
