-display and -e cmd line option interaction

[Clive Nicolson]

With lyx version 1.1.6fix2 of 18 May 2001 under RedHat Linux
I get the following error:

cvcv$ lyx -display :0 --export latex broad.lyx
Wrong command line option `-display'. Exiting.

Without the --export (or -e) option the command is ok. The
order of the options seems not to matter.
