From 6afb01f7c6ab4c40b4349706746f01f5d281735e Mon Sep 17 00:00:00 2001

Subject: Documentation: unbreak regex in show-ref manual
I am not sure why, but the regular expression "(?:\^\{\})" gets
rendered by asciidoc as "(?:\{})". The intent seems to be a regex
matching the literal string "^{}", so this rewrites the markup to
produce "(?:\^{})" as output.
