#171 Fold element does not fold following whitespace

[MNJ]

If I have a sequence of tags in a logical grouping, followed by some whitespace to visually separate them from the next logical grouping, if I fold each of the tags in the first group, when I fold the last tag in the sequence, the fold includes the following whitespace, making the two groups of tags run up against each other and losing my visual cue.

It would be useful to either not fold the whitespace, or, if this is seen as a useful feature for others, have an option to select whether to include or exclude following whitespace from a fold.
