CVS commit: src/bin/sh

["Robert Elz" <kre%netbsd.org@localhost>]

Module Name:    src
Committed By:   kre
Date:           Fri Nov 23 23:41:20 UTC 2018

Modified Files:
        src/bin/sh: redir.c

Log Message:
Fix the <> redirection operator, which has been broken since it was
first implemented in response to PR bin/4966  (PR Feb 1998, fix Feb 1999).

The file named should not be truncated.

No other shell truncates the file (<> was added to FreeBSD sh in Oct 2000,
and did not include O_TRUNC) and POSIX certainly does not suggest that
should happen (just that the file is to be created if it does not exist.)
