[aur-dev] FS#15043: patch for part 3 - package licenses link to Arch Wiki pages

 There is a feature request (FS#15043) for multiple package parsing
enhancements on AUR. One of them (part 3) asks for "arch and license
arrays can be converted to links [to Arch Wiki]".

 I checked out the "license" part, as I see the arch is not displayed
on AUR at the moment. Linking to common licenses might be an useful
idea, so here's a patch that does just that.
 Good code should speak for itself, but maybe I do elaborate a little:
 - I took the common licenses distributed in
/usr/share/licenses/common and uploaded them to the Wiki as
 - The code checks for these names in the licenses array, and if
there's any match, turns it into a link. If no match, just display it
as text.
 - Can handle multiple licenses in case needed.

 I can see some problems arise, though. I took the names of these
licenses exactly as it is in the directory, and that includes
capitalisation. E.g. "APACHE" and "PerlArtistic". Could match the
names case-insensitive, but that's a bad idea since the Wiki link is
case-sensitive... Thus, if some people use wrong capitalisation in
their PKGBUILD (like [1]) and complain that the link "does not work
0rz", then it is the reason... Namcap's check for licenses is
case-insensitive, so that's no help to prevent such problems.

 Anyway, here it is, let me know if there's any issue with the way
things are handled, or any other functionality that should be

Ps: I sent this out once before with the patch .gz attached, which
seemed to disappear. If later gets sent out, then my apologies..

Subject: [PATCH] add wiki link to common licenses in package details

The package licenses turned into wiki links in case of common licenses
(the ones that are already in /usr/share/licenses/common). Currently
the license name has to be the same as in the directory (same case too).
Not common licenses left alone and displayed as text. Can handle multiple
licenses in the rare case it is needed.
