class TexLogParser::PrefixedMultiLinePattern

Matches messages of this form:

Package tocbasic Info: omitting babel extension for `toc'
(tocbasic)             because of feature `nobabel' available
(tocbasic)             for `toc' on input line 132.

Note: Fails to pick up the fill message if lines get broken badly, e.g. in `000_pdf_fl.log:634`.
