This looks about correct, so I don't understand your question. In which way
this does fail? Don't make us solve riddles ;-)

Note that [:space:] includes "\n" (and vertical tabulator and other ilks
of space-y characters), so the (any "\n" "[[:space:]]") seems redundant
and "[[:space:]]" should suffice.

I'm not very fluent on Rx, but I'd double check whether it takes "[[:space:]]"
as syntax.
