6 char externs -- a lint suggestion

[Bill Fecht]

A lint option could be included which would allow one to have it
check all internal names to be unique up to 'n' significant characters.

Then, if the number of significant characters in internal names is made
machine dependent, a programmer could certify that a program is portable
to machines which need to limit the number of significant characters on
externs.

It would also make it easier for someone to make changes to a program
so that it would "fit" on their machine.
