distrib/notes/common/list-portmasters.pl: file removal
Remove list-portmasters.pl script.
We dropped that list from "main" some time ago.
Quote long .Ss2 title to avoid troff's limitation.
Troff is limited to 9 macro parameters and this title is 10 words, so
we lose the last word here when we pass arguments around.  We have
more titles like that but for now I wanted to commit only one just to
flag the problem.
More cleanup:
- simplify TOC handling and remove arg limit (from uwe)
- use Lk with explicit anchor text in some places
- do not allow official release builds when we can not derive the
  proper date from the buildid
Add "Oxford comma"
Improve heading a bit.  While here, use quotes to group some of the
words to avoid the 9-arg limitation of .Ss
