[vile] How can I run xvile like "gvim -f"?

[Chris Green]

I am invoking xvile from a firefox extension (textern if anyone is
interested, it's a replacement for "It's all text" which doesn't work
on Firefox 57 or newer).

For this to work xvile needs to stay in the foreground when invoked,
i.e. it needs to to what gvim does with "gvim -f".  Is there any way
to get it to do this or will I need some sort of wrapper?
