MFC r217133: sed: Try hard links to make -i target available continually.

2011-01-25T23:02:25Z

When creating a backup file, sed renamed the original before renaming the changed copy into place, leading to a short time when no file with the original name was present (usually only visible on SMP systems). Try creating the backup file using a hard link instead, avoiding this problem. If creating the hard link fails for any reason, fall back to the old rename method. When not creating a backup file, sed already renamed the changed copy onto the original. This remains unchanged. PR: bin/153261 Submitted by: Pedro F.

IEEE Std 1003.1, 2004 Edition states: "The escape sequence '\n' shall match a embedded in the pattern space." It is unclear whether this also applies to a \n embedded in a character class. Disable the existing handling of \n in a character class following Mac OS X, GNU sed version 4.1.5 with --posix, and SunOS 5.10 /usr/bin/sed. Pointed by: Marius Strobl Obtained from: Mac OS X
