779fedd7c3021f013726c8f53cb9e66c54637ebf added a warning,
which is nearly identical to an existing one, but didn't change the
description of the existing one to encompass both. This rectifies that.
=item Unterminated \g{...} pattern in regex; marked by <-- HERE in m/%s/
-(F) You missed a close brace on a \g{..} pattern (group reference) in
-a regular expression. Fix the pattern and retry.
+(F) In a regular expression, you had a C<\g> that wasn't followed by a
+proper group reference. In the case of C<\g{>, the closing brace is
+missing; otherwise the C<\g> must be followed by an integer. Fix the
+pattern and retry.
