Syntax highlighting bug on regular expressions containing '#' inside a conditional

[variacc]

The Perl syntax highlighting breaks on regular expressions that implicitly use the default input variable and contain the '#' character.
The syntax highlighting breaks if the following conditions are met:

• The regex implicitly uses the default $_ variable
• The regex is not the first item in the conditional
• The regex follows an 'and' or 'or' operator

The rest of the line following the # is highlighted as a comment.

if (/^#/ and $something) { moo(); } # Syntax highlighting is good
if ($something && /^#/) { moo(); } # Syntax highlighting is good
if ($something and /^#/) { moo(); } # Syntax highlighting breaks!

Using m// instead of // (i.e. m/^#/) seems to workaround this issue.

The way I would describe why it doesn't affect the first two cases is that there isn't something to the left of the matching operator // that isn't one of a few characters of operators (&, |, and ~ are the only I've found) or the opening parenthesis (.
