[PATCH v3] git-merge: rewrite already up to date message

From: Josh Soref <jsoref@gmail.com>

Usually, it is easier to read a message if it makes its primary point first, before giving a parenthetical note.

Possible messages before include: ` (nothing to squash)Already up to date. ` and `Already up to date. Yeeah! `

After: `Already up to date (nothing to squash). ` and `Already up to date. `

Localizations now have two easy to understand translatable strings. (All localizations of the previous strings are broken.)

    git-merge: rewrite already up to date message
    
    GitHub Actions show things like:
    
     * branch                  master     -> FETCH_HEAD
     (nothing to squash)Already up to date.
    
    
    There was a code path where it would say:
    
    Already up to date. Yeeah!
    
    
    It is believed that other than being troublesome for localizers, this
    message added no value, so it's being removed.
    
    Usually, it is easier to read a message if it makes its primary point
    first, before giving a parenthetical note.
    
    The expected results are:
    
     * branch                  master     -> FETCH_HEAD
    Already up to date (nothing to squash).
    
    
    As well as an easier chance for localizers to actually translate the now
    two messages. (As they don't have to fight string pasting. Which is a
    localization sin.): Already up to date. Already up to date (nothing to
    squash).
    
    This commit should change that. Other than breaking anyone who actively
    parses the output and all the localizations (and giving localizers a
    real chance at localizing these messages), this shouldn't have much
    impact.
    
    Changes since v2:
    
     * finish_up_to_date now figures out the answer on its own to address
       feedback from Eric Sunshine
    
    -- Yes, I'm well aware of localization rules. But as Eric Sunshine
    noted, the code was already making a mess of things. I didn't want to
    make invasive changes. I actually wrote roughly what Eric proposed as an
    earlier implementation, but the various complexities, including trying
    to figure out what the yeah was for and who cared about it, made me
    really wary of proposing such a significant change.
