Perl Syntax Highlighting: Issue with highlighting in certain situations when using regex

[chriscapaci]

• VSCode Version: 1.17.2
• OS Version: Windows 10

Steps to Reproduce:

1. Download attached file and remove .txt extension so extension is .pl (Perl code)
2. Open file syntax_highlighting_issues.pl in VSCode
3. Observe syntax highlighting (comments explaining what's going on)

NOTE: All usages of regex's in the code are valid as the project I work on contains all of them. Some may be uncommon, but they are valid and work, so highlighting should work with them.

Reproduces without extensions: Yes
