Commas not allowed in License tags

[Kevin Kofler]

Hi,

this has recently come up in a discussion about the License tags of gcc and 
mingw32-gcc. The guidelines are very clear here:

https://fedoraproject.org/wiki/Packaging:LicensingGuidelines#Multiple_Licensing_Scenarios

> If your package contains files which are under multiple, distinct, and
> independent licenses, then the spec must reflect this by using "and" as a
> separator.

There's even an example to clarify this:

> License: Python and LGPLv2+ and BSD

This is also reflected in the FAQ:
https://fedoraproject.org/wiki/Licensing:FAQ#How_should_I_handle_multiple_licensing_situations.3F

It shall be noted that commas are also not allowed in dual-licensing 
scenarios, where "or" is the required separator.

Thus the following License tag is NOT valid:
> License: GPLv3+, GPLv3+ with exceptions and GPLv2+ with exceptions

It should be fixed to read:
License: GPLv3+ and GPLv3+ with exceptions and GPLv2+ with exceptions

The goal here is not to write stylistically nice English, but to write 100% 
unambiguous, automatically parsable text. The rpmlint tool is correct in 
complaining about this.
