read_poll RE: PATCH: Zpty cleanup (merge 13061 with 13116)



Unless I completely miss something:

read_poll tries to read from fd and stores the character it has read in
readchar; that is cmd->read when called from checkptycmd. But this value does
not seem to be used anywhere in read loop that looks like read_poll simply
eats up this readahead char ...
