The help string for `start-process' does not say what happens to
stderr for the spawned process. It just says:
Process output goes at end of that buffer, unless you specify
an output stream or filter function to handle the output.
I tested this (on Windows XP) and it seems both stderr and stdout go
to that buffer. I tried reading the C code in process.c, but quickly
got lost.
I suggest that the help string be modified to:
Process output (both standard error and standard output) goes at
end of that buffer, unless you specify an output stream or filter
function to handle the output.
Is there a way to separate standard error from standard output for the
spawned process? That would probably be useful in some situations.
