Short update. Since I cannot find a file name quoting which satisfies
both pscp and MS Windows scp, I've decided to add a new user option
tramp-use-ms-dos-quote-argument. It's default value is nil, but users
can change it to non-nil. In that case, Tramp would apply the changed
file name quotation for scp arguments, i.e. replacing a double quote by
two double quotes, and putting everything into a start/stop double
quote.

It doesn't work yet, and I'm still running my test suite in many
constellations, so likely there's nothing to commit for today.

Thanks for the tip, I'll try this next.

Hmm. Yes. But I have no idea how to check it w/o collateral damages (and
you are not the first one who has asked). Proposals welcome!
