[PATCHv2 maint] git-svn: Fix git svn log --show-commit

[Bernt Hansen <bernt@norang.ca>]

From: Michael J Gruber <git@drmicha.warpmail.net>

From: Michael J Gruber <git@drmicha.warpmail.net>

git svn log --show-commit had no tests and, consequently, no attention
by the author of

b1b4755 (git-log: put space after commit mark, 2011-03-10)

who kept git svn log working only without --show-commit.

Introduce a test and fix it.
