PATCH: time time

[Sven Wischnowsky <wischnow@informatik.hu-berlin.de>]

[ sunsite sleeping again, great ]

Just found this on the Debian bug list...

Doing `time time' can be deadly. The problem is that it can't handle
time-in-a-time, but it still takes the second `time' as a special
token.

Dunno if this fix is correct, it makes the second `time' be taken as a 
command name. At least it fixes the bug and trying to measure the
execution time of `time' without a command doesn't make sense
anyway. We could also make it report an error (bash does that, ksh
reports the times of `time' without arguments (hm) and the DU sh does
what zsh does with this patch -- measure execution times of the
external command `time').

Bye
 Sven
