Bug#649402: [PATCH] time overestimates max RSS by a factor of 4

[Richard Kettlewell]

Package: time
Version: 1.7-23.1

$ \time grep VmRSS /proc/self/status
VmRSS:       524 kB
0.00user 0.00system 0:00.00elapsed 0%CPU (0avgtext+0avgdata 
3072maxresident)k
0inputs+0outputs (0major+238minor)pagefaults 0swaps
The reason is that it converts ru_maxrss from pages to kilobytes, but it 
is in kilobytes already (see 'man getrusage').  The patch removes the 
erroneous conversion.
