Steve, First off, this patch does fix the large paste problem. Thanks for this!
However, there are a couple of problems with this patch. For example,
this makes bash run from a command prompt (or a shortcut) treat every
character as a ^D. Bash run from an xterm/rxvt works fine. /bin/sh
ignores Enter (or ^J, or ^M). Running 'bash -c "echo BLAH && exit"' from
a command prompt works, however, running "bash -c 'echo BLAH && exit'
results in
C:\cygwin\bin>bash -c 'echo BLAH && exit'
BLAH
'exit'' is not recognized as an internal or external command,
operable program or batch file.
C:\cygwin\bin>
and "bash -c 'echo BLAH && exit '" (with a space after exit) echoes BLAH
and exits the originating command prompt. Putting any character after the
space results in the same behavior. I'm attaching an strace of bash
running under command with this problem.
Adding 'tty' to CYGWIN doesn't affect the outcome. Setting TERM to
'cygwin' in xterm/rxvt doesn't reproduce the problem - this only happens
in a command shell.
I'm unable to track this down further. Hope this helps. Please let me
know if you need any additional info.
