[aprssig] spaces in object names

[Randy Love]

I believe the basis of print vs. non-print has to do with the c
function isprint(), where a char is sent to it to determine if the
char is printable or not. A space character (Hex 20) will pass
isprint() as true. A null (Hex00) or control character, such as Hex04,
will not.

It isn't so much ambiguity as not being clear on the source of the
terminology. If Bob clears up the spec, then that's great. Although it
doesn't cause anything to be printed by a printer, it is a printable
character, otherwise text would be really messy to read
