[PATCH] Documentation: do not misinterpret pull refspec as bold text

[Jonathan Nieder <jrnieder@gmail.com>]

Use the {asterisk} entity to avoid mistreating the asterisks
in "(e.g., refs/heads/*:refs/remotes/origin/*)" as delimiters
for bold text.

>From a quick search with 'git grep -e "\*.*\*"', this seems to
be the last example of this particular formatting problem.
