Author: ed Date: Sun Mar 8 19:09:55 2009 New Revision: 189542 URL: http://svn.freebsd.org/changeset/base/189542 Log: Don't disable CR-to-NL translation when waiting for data to arrive. A difference between the old and the new TTY layer is that the new implementation does not perform any post-processing before returning data back to userspace when calling read(). sh(1)'s read turns the TTY into a raw mode before calling select(). This means that the first character will not receive any ICRNL processing. Inherit this flag from the original terminal attributes. Even though this issue is not present on RELENG_*, I'm MFCing it to make sh(1) in jails behave better.
