bug#49192: cperl-mode: Syntax highlighting wrong for modifier "for /regex/" (patched)

["E. Choroba" <choroba@matfyz.cz>]

[-- Attachment #1: Type: text/plain, Size: 219 bytes --]

The following lines are highlighted correctly:

  print while /./;
  print if /./;

But the following two aren't:

  print for /./;
  print foreach /./;

(In reality, probably only useful with /g).

Patch attached.

Subject: [PATCH] cperl-mode: Fix syntax highlighting for a regex after a for
 modifier

The following lines should be highlighted the same:

  print while /a/;
  print if /a/;
  print for /a/;

"for" behaved differently, the regex wasn't highlighted at all.
