[Svnmerge] Minor command line bug

[Blair Zajac]

Hello,

If I type

$ svnmerge.py -v
Traceback (most recent call last):
   File "svn-1.3.x-branch/contrib/client-side/svnmerge.py", line 1226, in ?
     main(sys.argv[1:])
   File "svn-1.3.x-branch/contrib/client-side/svnmerge.py", line 1168, in main
     assert 0, "command not handled: %s" % action
NameError: global name 'action' is not defined

I don't have the time right this second to fix this myself, otherwise I would.

Regards,
Blair
