Well, if wouldn't work in the select() replacement, but if it were
implemented in fd_buffer_input, then extra data could be stored in the
buffer structure. I'd prefer the select() replacement, but if needed
this could be used as a fallback.

Hrm? If there was a select() function that worked to the POSIX
semantics I already forwarded, CVS's needs should be satisfied.

No. There was a good reason for moving to fd_buffers from stdio
buffers, though I can't recall it off the top of my head, and it would
be pretty hard to extricate them now anyhow.
