	The culprit (mostly) this time is ps itself.  It's "smart" about your
terminal line size.  Of course, smart can appear to be very dumb
sometimes....

	On my system (RH 7.2), ps efww gives me long lines that ignore the
terminal line length.  "ps -ef | grep ." gives me the same: full width
of the terminal.  I think it uses the "COLUMNS environment variable,
which is set to the width of the term.

	I can't explain the 63 char problem going through grep, sorry.
