[Bug 913292] [NEW] 'time' ignores arguments (such as '-f') and discards them as commands

[Sebastian Lai]

Public bug reported:

As defined in the manpage of 'time' (see
http://manpages.ubuntu.com/manpages/natty/man1/time.1.html), the 'time'
command should understand the following command:

       time -f "%E real,%U user,%S sys" ls -Fs

However, it seems to ignore the '-f' argument:

       $  time -f "%E real,%U user,%S sys" ls -Fs
       -f: command not found

       real	0m3.423s
       user	0m0.232s
       sys	0m0.188s

That could be considered undefined behaviour, for example, when shell
scripts depend on the '-f' flag (or other flags, for that matter).
