Subject: Revert "Support all perl variable declarators and prefixes"
X-Git-Tag: emacs-26.1-rc1~69
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=f8cad16bb3272a8069b3008019f9d18516aef1a5;p=emacs.git

Revert "Support all perl variable declarators and prefixes"

It highlights normal variable names in perl programs (Bug#30812).
* lisp/progmodes/perl-mode.el (perl-imenu-generic-expression)
(perl-font-lock-keywords-2): Restore values prior to Bug#27613 fix.

Don't merge to master, we will fix Bug#27613 properly there (it's too
close to release to do that on emacs-26).
