That looks promising. Thanks.

Might want a few more. But this should only apply to these selected 
commands.

I want this to be as frictionless and quick as possible. Opening up an 
editor is a bit much.

This made me realise though that I don't *need* it to be quoted, I would 
be happy if it would escape those chars individually, either as I type 
or on accepting the line.

I found this very similar question[1] from a few years ago which solves 
the problem for quotes. I'll also try this and see if it'll work for 
other special chars too.

Will have a play with all this when back from holiday though. Silly of 
me to ask a question just before being AFK for a few weeks.

I'll have a read through `url-quote-magic` too, which seems to do 
something similar.

Thanks.
