Enable 'm' flag on regex for multi-line tests

JohnDumbell · JohnDumbell · commit bcc521127d12 · 2018-05-10T15:54:28.000+01:00
This is a change to the multi-line match option to enable traditional regex multi-line matching. The m flag causes ^ and $ to actually match correctly on new line/carriage returns, where before the match was actually on the entire file so ^ was just beginning of file $ was the end. This also fixes a few tests' failure condition where this subtle difference wasn't noticed and '^warning: ignoring' is used.
