Categories containing "++" make gnatsweb crash |

Hello,
When categories contain a "++" in their name, gnatsweb crashes with the
following error:
Nested quantifiers in regex; marked by <-- HERE in m/^client-c++ <--
HERE $/ at /home/gnats/cgi-bin/gnatsweb.pl line 1610, <SOCK> line 2173.
which points to the line containing grep in this piece of code:
sub edit
...
if (fieldinfo ($_, 'fieldtype') eq 'enum')
{
my $default = $fields{$_};
# Check whether field value is a known enumeration value.
if (!(grep /^$default$/, @$values))
{
push(@$values, 'unknown') if (!grep /^unknown$/, @$values);
$default = 'unknown';
}
print popup_or_scrolling_menu($_, $values, $default),
"</td>\n</tr>\n";
}
...
When I replaced the name of the category client-c++ with client-cpp and made
all necessary changes in the PR's it works fine. The example file
"categories" doesn't warn against this and in there is an example which
wouldn't work (g++).
There are several solutions:
1) restrict the use of special characters in category names and correct
"categories"
2) correct the use of grep in gnatsweb.
3) ...
My preference goes actually to the first solution.
