Sure, that sounds fine by me.  Truth to be said, I could not came up
with a good name so I escaped into the “smart” realm. ;)

The second state is `delete-horizontal-space' (with backward-only being
nil) essentially, but yes, I thought about making something even more
configurable, like accepting a list of states or something, but I didn't
want to make the function too complex, and rather get it to do what
I think would be the most useful thing.
