[PATCH][OBVIOUS] Add IntegerRange for Wcatch-value= option.

["Martin Liška" <mliska@suse.cz>]

[-- Attachment #1: Type: text/plain, Size: 538 bytes --]

Hi.

This is small documentation fix, I'm going to install the patch
as obvious.

Now we display:

$  ./xg++ -B. --help=c++  | grep catch-value=
  -Wcatch-value               Warn about catch handlers of non-reference type.  Same as -Wcatch-value=.
  -Wcatch-value=<0,3>         Warn about catch handlers of non-reference type.

Thanks,
Martin
