BTW, it turned out to be fairly simple after all, but I could see this
only after passing it through (insert ...) in a temporary buffer, so
that all the double backslashes stopped looking like a drunkard's
nightmare. So even such a rudimentary "tool" (basically, temp buffer
and `insert') did help a lot.
