This fixes the issue that something like [
http://url/
link]s (i.e. text directly following
the closing square bracket) would produce something ugly in printing:
link (
http://url/)s
Now it finishes the word first:
links (
http://url/)
The given example seems pointless, but in languages other than English this happens more
frequently.
Make sure you use the established linktrail; some languages don't use
spacing between words as a separator.
