** Description changed:
Backgrounded process with input redirected from a pipe has wrong
information in /proc//cmdline (it seems to contain the parent
process command line). So while the jobs listing shows correct command
line for the process, utilities such as ps do not. Can be reproduced
This problem appears to be independent of the parent shell as it has
been observed with bash, ksh, sh.
