[PATCH 4/4] Remove global wrap_here function

[Tom Tromey <tom@tromey.com>]

This removes the global wrap_here function, so that future calls
cannot be introduced.  Instead, all callers must use the method on the
appropriate ui_file.

This temporarily moves the implementation of this method to utils.c.
This will change once the remaining patches to untangle the pager have
been written.
