Subject: Tweak to r28390:
X-Git-Tag: 1.31.0-rc.0~50333
X-Git-Url: https://git.cyclocoop.org/%28%28?a=commitdiff_plain;h=d197cc8faf2c49d19628171d6f4d23cc36d76055;p=lhc%2Fweb%2Fwiklou.git

Tweak to r28390:
Instead of disabling the 'Compare selected revisions' button when there's only one revision, just don't show it.
We don't show any radio buttons in this case either, so there's nothing to consider submitting if we wanted to; it's cleaner to just leave it out.
