Hello David.

Unfortunately, this format is not recognized by gcc-changelog script and
so the corresponding PR entries were not added to the generated ChangeLog
entries. The currently supported regex is:

pr_regex = re.compile(r'\tPR (?P<component>[a-z+-]+\/)?([0-9]+)$')

which prevents parsing an entries not being standalone.
Anyway, I updated gcc/analyzer/ChangeLog manually.
