Well, it's not just my typical wish of consistency in what
the functions should do... it's also a matter of consistency with
Emacs own TODO list:
We have an entry in the TODO list requesting exactly what i am
suggesting :-)

Question:
can we conclude that following entry in TODO file has being
fulfilled by Daiki work?

The entry mentions `start-process' which currently cannot do the
stdout, stderr separation.  As pointed out by Michael, 
`start-file-process' either.
If we understand this entry as:
-----
Give Emacs the ability to direct standard-error
output to a different filter on asynchronous processes.

then it's already done and we can drop such entry from TODO file.
