[alexandria-devel] Add mkstr and simplify of 'symbolicate

[Nikodemus Siivola]

Just to weigh on this quickly:

Given that we have PRINC-TO-STRING, PRIN1-TO-STRING, and
WRITE-TO-STRING, an N-argument version should probably exist in these
variants too, and be named along those lines.

Contracted names will not be added to Alexandria, though, unless
supported by existing tradition (Zetalisp, etc -- PG doesn't count.)

(And sorry for the delay on this -- as well as other -- Alexandria issues.)

Cheers,
