I'm tempted to have atolx() skip leading zeroes, and then base 16 if the first
character is an x and base 10 otherwise. Except supporting the - basically means
open coding the sucker...

Anyway, my _real_ question is, if I'm yanking octal from dd= should I yank it
from everywhere? I still think it's useful for "printf %d 0123" to be able to
cope with it (especially since "printf %o 668" prints 1234). And maybe $((0123))
needs it too?

No clue where to draw the line on this one. Hmmm...
