Let space-joined path segments keep their trailing extension

A space-separated segment only counts as part of an unquoted path when
it contains '/' or '.', but the segment pattern also had to *end* with
one of those, so greedy backtracking cut '/x/face cropped.png' at
'cropped.' and left the extension out of the match. Allow trailing word
characters after the last '/' or '.' so the full extension is absorbed.
Prose words after a path (' and', ' at') still contain neither
character and are still excluded.
