 The attached patch fixes sane-frontends' livecheck.  Before:

 {{{
 $ port livecheck
 Error: cannot check if sane-frontends was updated (regex didn't match)
 }}}

 After:

 {{{
 $ port livecheck
 sane-frontends seems to have been updated (port version:
 45efdeabbf07f38ef0f8b3ca054b1cdc9fbb3f7, new version:
 1928f945eefa3b97b5c76d586082435bb23c2969)
 }}}

 Please note I used an old SHA1 for ${git.branch} to get the "After"
 output.  The most recent version is indeed 1928f9 and 'port livecheck'
 should really output nothing until the next time a commit is pushed to the
 master branch of the sane-frontends' git repo.
