I don't know you are the right person to ask, but I found you
committed some of 8bit cleaning in src/bin/sh.
Shell script which contains here-document of 8bit text sometimes dumps
core. For example, please test this script in 4.1 or -current.
#!/bin/sh
cat <<EOF
[8bit text which contains 0x82 character]
EOF
And, if I use 'EOF' instead of EOF, it works fine. Do you have any
idea about this behavior?
After at a glance of sources, 0x82 is used as CTLVAR control
character. I think this should be escaped as CTLESC CTLVAR before
examining variable substitution whether here-docuement is quoted or
not.
