[TYPO3-caretaker] Check TYPO3_CONF_VARS with regex, e.g. for enableDeprecationLog

[Peter Kraume]

Hi all,

I'd like to check my TYPO3_CONF_VARS for disabled deprecation log.

The test should throw a warning, if [SYS][enableDeprecationLog] is not 0 
or '' (empty).

I tried this syntax but it doesn't work:

SYS|enableDeprecationLog:regex:0|( )

Any hints for me?

Thx
Peter
