Subject: [PATCH v4 05/10] commit-graph write: more descriptive "writing out" output

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Thu, 22 Nov 2018 15:39:17 +0000

Make the "Writing out" part of the progress output more
descriptive. Depending on the shape of the graph we either make 3 or 4
passes over it.

Let's present this information to the user in case they're wondering
what this number, which is much larger than their number of commits,
has to do with writing out the commit graph. Now e.g. on linux.git we
emit:

    $ ~/g/git/git --exec-path=$HOME/g/git commit-graph write
    Finding commits for commit graph: 6365442, done.
    Annotating commit graph: 2391666, done.
    Computing commit graph generation numbers: 100% (797222/797222), done.
    Writing out commit graph in 4 passes: 100% (3188888/3188888), done.

A note on i18n: Why are we using the Q_() function and passing a
number & English text for a singular which'll never be used? Because
the plural rules of translated languages may not match those of
English, and to use the plural function we need to use this format.
