Anyone know of a way to force the sorting to occur only within the
field selected ?  ie. with the following region selected:

a 789 blah
b 456 blha
c 123 bleh

C-u 2 M-x sort-field-only

would give

a 123 blah
b 456 blha
c 789 bleh

Anyone know of a package that does this?  Or perhaps I'm missing
something that emacs already does.

Even better would be a way to sort based on a rectangle.

A sort-rectangle function would be ideal for me.
