requestsync can't handle third parameter (basever) but advertises it in usage

This patch fixes the issue for me.

The heat constrains my brain.

The fix will be uploaded soon, thanks.

devscripts (2.10.5ubuntu1) gutsy; urgency=low

  * Merge from Debian unstable
  * Remaining Ubuntu changes:
    - requestsync:
      + New script.
      + ask for explanation why Ubuntu changes can be dropped (patch from
        Adrien Cunin)
      + use gpg2 for signing if available
      + General cleanup, mostly to stop mixing tabs and spaces.
      + Add a -n option, to show that this is a new source package according
        to Ubuntu.
      + Add a -s option, that will subscribe the relevant sponsor group
        instead of ubuntu-archive.
      + Look up the Debian component, and support downloading changelog
        entries from components other than main.
      + Print a meaningful error rather than throwing an exception if
        apt-cache madison contains nothing.
      + Don't confirm the bug when -s (sponsorship) is passed
      + Giving base version as a third argument works again, thanks Kjell
        Braden. (LP: #119313)
    - debchange: add --security option, which acts like --nmu, but adds
      security update template instead of NMU template to changelog.
    - debuild:
      + Add some heuristic checks about the Ubuntu merging policy. Issue a
        warning if a merge does not use -v or describe the remaining Ubuntu
        changes.
      + Keep DISPLAY, XAUTHORITY and GNOME_KEYRING_SOCKET environment
        variables around for safe keeping before we destroy the environment,
        and re-set them before running debsign. (LP: #78165)
  * Ubuntu changes dropped:
    - debchange:
      + Add support for Ubuntu versioning.
      + Allow UNRELEASED in Ubuntu distro check.
      + Accept Ubuntu distribution "gutsy" and use it by default on Ubuntu.
