Subject: Make the multi-line comment regular expression a bit easier to read.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e4b2731a25c071407d90c6c593a226574e9c36f9;p=mesa.git

Make the multi-line comment regular expression a bit easier to read.

Use quoted strings for literal portions rather than a sequence of
single-character character classes.
