Why goexpect use TeeWriter to handle both stdout and stderr

[fangxlmr]

Hi, the crew, great job of this package!

goexpect/expect.go

Line 1161 in b5b7712

go rdr(sErr)

As said, goexpect wirte stdout and stderr both to an io.Writer (if any). Isn't it resonable to handle them separately?
BTW, tee command itself merely captures stdout. ;P

Hey thx. for the feedback @fangxlmr.

Sounds reasonable to me, currently my cycles are very limited so could be a while before I'll have a chance to dig into this.

PRs are always prioritized though.. :)

Well, a single teeWriter-like option for handling both stdin and stdout does has its advantange, whereas an option to handle them separately may also have its own position.

Yeah GoExpect do have the concept of options, should probably be implemented as a new option with the default being the current way it's handled.
