[PATCH v2 1/2] gitk: drop quotes in copysummary format

[Denton Liu <liu.denton@gmail.com>]

In an earlier commit[1], git learned the 'reference' pretty format. This
format was very similar to the format that copysummary used but it omits
the quotes surrounding the commit's subject. Remove the quotes from the
format in copysummary in order to match the 'reference' pretty format.

It seems the consensus is that the unquoted form is used more often
anyway[2] so this change should be acceptable.
