Review Board SVN (deprecated)


When you only give one revision for post review, you expect that only that revision only will be posted.

However, with post review today and svn, if you say --revision-range=r500 that will become r500:HEAD

This patch changes it to r459:r500, which are the changes generated by revision 500 only.
Ran it on my local instance with --revision-range=r457

This became: .../@r456 to .../@r457 which is what I expected
