Yes, thats more or less what I expected to be the root cause of the problem.

Ok, thanks, that sounds promising. OTOH, is the use of "\\S-" really
mandatory, couldn't a more robust construct be used, either something
like this (untested) regexp:

,----
| "[^[:space:]\\n]+"
`----

or a custom character-class that consists of whitespace plus newline?
