Teach run_command how to setup a stdin pipe
Sometimes callers trying to use run_command to execute a child process will want to setup a pipe or file descriptor to redirect into the child's stdin. This idea is completely stolen from builtin-bundle's fork_with_pipe, written by Johannes Schindelin. All credit (and blame) should lie with Dscho. ;-) Signed-off-by: Shawn O.
