tvl-depot/third_party/gerrit/syntax_highlight_rules_pl.patch
Luke Granger-Brown 89b3ab939b feat(gerrit): Syntax highlight rules.pl as Prolog.
This adds support for overriding the detected languages based on the
filename - we assume here that rules.pl will always map to a Prolog
file.

I could've overridden the entire default language to Prolog, since it's
unlikely that we'll have any Perl here, but given the relative
popularity of the two languages I opted to just override the file we
know we'll have (because it's used by Gerrit itself).
