Prior to this, the `--no-gui` option was not documented in the manpage.
This commit introduces this into the manpage

Reading the whole of this file before applying this patch, I notice
that we have descriptions of negative forms only for some but not
all options. "--[no-]symlinks" and "--[no-]trust-exit-code" are
already there, but not this one.  

Shouldn't the patch be more like

    ---gui::
    +--[no-]gui::

to be consistent with its existing friends, though?
