[PATCH] fetch doc: escape asterisk in --tags paragraph

[Ramkumar Ramachandra <artagnon@gmail.com>]

Currently, the paragraph corresponding to the --tags option in
git-fetch(1) looks like:

  -t, --tags
      This is a short-hand for giving "refs/tags/:refs/tags/" refspec
                                                 ^^^^^^^^^^^
						 this is in bold

This happens because the corresponding text in fetch-options.txt is
"refs/tags/*:refs/tags/*"; asciidoc renders the text between the two
asterisks in bold.  Escape the first asterisk, correcting the text.
