forever

Changes (by rbeezer):
* status: needs_review => needs_info
Comment:
OK, that makes sense, I was reading the code, not the doc string. Three
ideas:
* Probably should be {{{solve_right}}}.
* How about a more descriptive name, like {{{solve_right_precomputed}}}?
* LU decomposition now works for rectangular matrices (#10839). I'd
think it would make the most sense to cache the "LU factor" matrix just
for this purpose. That's the ''square'' matrix where L and U share space
and the diagonal 1's are not present.
