[QGIT PATCH] Rework the commit confirmation box a bit

[Abdelrazak Younes <younes@lyx.org>]

The problem was that the dialog was too big for my whenever too many files
were changed. Now, the list of changed files is only shown whenever they are
less than 20; otherwise it is shown in the detailed text accessible though
the 'Show Detail' button.
