Bug Description

With default settings, the Unix `time` program runs output together in an ugly, unreadable way, when run from a Makefile.

Trace:

$ time echo '42'
42

real 0m0.000s
user 0m0.000s
sys 0m0.000s

$ cat Makefile
all:
 time echo '42'

$ make
time echo '42'
42
0.00user 0.00system 0:00.00elapsed 0%CPU (0avgtext+0avgdata 628maxresident)k
0inputs+0outputs (0major+206minor)pagefaults 0swaps

To workaround this issue, I can force `time` to use a better format, by running it with the "-p" flag.

$ cat Makefile
all:
 time -p echo '42'

$ make
time -p echo '42'
42
real 0.00
user 0.00
sys 0.00

But I would prefer not to have to do this. Could we please have `time` detect the tty status and default to "-p" more appropriately?
