suggested addition to 'date'

[Lyndon Nerenberg]

I would lose the arbitrary restriction on line length by dropping linebuf 
and using getchar()/putchar() with a test for \n to determine when to 
emit the timestamp.

There's also the restriction on only being able to timestamp one stream. 
I can see where it would be useful to be able to timestamp both stdout and 
stderr; with 'date -s' you have to combine them.  However adding support 
for this argues for a separate program, as that sort of functionality 
doesn't belong in date.
