 Mr> i'm pretty sure that's intentional and certainly seems like it should be.

It's not what I would expect.  If you specify a field length for printf(), it
should fill that entire field up to that length.  Otherwise, the results can be
unexpected and ugly.  The main uses for specifying a field length are to align
text and filling a space when overwriting existing text on the screen.  I would
expect printf() to only count visible/printable characters in the length of a
string you give it.

 Mr> who's name or other variable would have color codes in it, though?

Anything where color is desired.. :P
