Comment (by michaelld):

 > I didn't do a PR because I didn't think it necessary and didn't want to
 decide for you where and how you put the patchfiles into the Portfile.

 Understood. If you add the new patches to the end of the patches section
 with their own new (#) & explanation, that's perfectly find. I hope the
 patching MO in Qt4-mac is sufficiently clear to any experienced programmer
 to be able to follow suit.

 > Now, if a PR means a CI will do those test builds on various OS versions
 then that changes things a bit...

 Yes, yes it does! YA reason for PRs! The MP PR system can be a little
 daunting, but if you try it out: go with the flow & don't worry too much
 about precision!
