[PATCH] git-gui: suppress RenderBadPicture X error caused by Tk bug

Due to a bug in Tk, git-gui almost always (unless git-gui is closed
right after starting) produces an X window error message on exit,
something like:

X Error of failed request:  RenderBadPicture (invalid Picture parameter)
  Major opcode of failed request:  150 (RENDER)
  Minor opcode of failed request:  7 (RenderFreePicture)
  Picture id in failed request: 0x3a000dc
  Serial number of failed request:  1965
  Current serial number in output stream:  1980

Respective Tk bug report is here:

http://sourceforge.net/tracker/?func=detail&atid=112997&aid=1821174&group_id=12997

This bug is triggered only when the send command is blocked via
rename send {} . The following patch re-enables send just before
quiting git-gui to suppress the error.
