This will cover most ChangeLog files, but I'd rather move your new
restricted date regexp to a new special variable `change-log-date-regexp'
(and using it in `change-log-font-lock-keywords'), thus allowing users
to override it by file local variables in ChangeLog files with a different
date format.

Also it seems that the format for arbitrary text in ChangeLog files is
a line beginning with two spaces.  Look for example in the same file
emacs/src/ChangeLog for the copyright statement.  It is indented with
two spaces, probably with the intention to not highlight it as a date:
