While reading command-line arguments from /proc entries, I noticed that
the eventual trailing spaces of the last argument are stripped, i.e if
I run
% cat '/tmp/a file '
I will get '/tmp/a file' as argument in the proc entry.
The get_array() function in array.c is responsible for that. It says
it removes trailing spaces used to pad argv/envp. But it doesn't look
like that this is necessary because if I remove that my system still
works nicely and the procps problem is corrected.
I enclose the patch in this mail. Could you please tell me if it is
okay, and then forward it to the appriopriate person?
Thanks,
Yves.
