* Does a very careful checkin of the file "user", and tries not to spoil its
* modification time (to avoid needless recompilations). When RCS ID keywords
* get expanded on checkout, however, the modification time is updated and
* there is no good way to get around this.
*
* Returns non-zero on error.
