Afte re-testing with `graph', it seems the problem is not due to
`auto-connect'.  I've probably think it was because of caching, oops.

But the following workflow still has the same problem:
--8<---------------cut here---------------start------------->8---
process proc (with output)
  packages "coreutils"
  outputs : file output
  # {
    rm -f {{outputs}}
    for i in $(seq 3); do
      date >> {{outputs}}
      sleep 1
    done
  }

define A : proc "A.out"
define B : proc "B.out"
define C : proc "C.out"

workflow parallel
  processes
    graph
      C -> A B
--8<---------------cut here---------------end--------------->8---

A and B should run in parallel, but they do not.
