bug#11014: cperl syntax highlighting breaking on certain complex regular expressions |

Syntax highlighting in cperl-mode breaks for certain (or perhaps all)
complex regular expressions modified by /e and/or /x.
Here are 2 examples of offending code:
example 1 -----
sub greek_with_latin
{
my ($self, $ref) = @_;
# $self->{perseus_morph} = 0;
$$ref =~ s/([^\&]*)([^\$]*)/
my $gk = $1 || '';
if ($gk)
{
$self->{perseus_morph} ?
$self->perseus_handler(\$gk,
'grk')
:
$self->{greek_handler}->(\$gk);
}
my $lt = $2 || '';
if ($lt)
{
$self->{perseus_morph} ?
$self->perseus_handler(\$lt,
'lat')
:
$self->{latin_handler}->(\$lt);
}
$gk.$lt;
/gex;
}
-----
example 2 -----
$$ref =~ s/'/$self->{ibycus4} ? '{\'}' : '\'\''/ge;
-----
Lines of code coming after "blocks" like these are all highlighted as
though they were quoted (at least that's what seems to be the case
judging from the color).
