Remove in_user_command

While working on the next patch in this series, I found that the
global in_user_command is not used.  This patch removes it.  (I didn't
think to check Insight until submitting this series; and it's not very
convenient to do so, so if someone has it checked out and could look
at it, that would be nice.)
