OK, how about this:

:L -- seems that bmake's use for this is kinda pointless; returning the
name of the variable; we could swap that usage over directly.

:U -- with bmake has non-optional arguments, so for example:

${VAR:U} - pmake behaviour

${VAR:Uval} - make behaviour.

Would that be acceptable?  I can get a patch in if that's popular.
