[PATCH 03/17] Documentation: unbreak regex in show-ref manual

[Jonathan Nieder <jrnieder@xxxxxxxxx>]

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.
