Module Name: src
Committed By: dholland
Date: Fri Jan 1 19:34:59 UTC 2010
Modified Files:
src/bin/sh: cd.c sh.1
Log Message:
Make the cd builtin accept and ignore -P, which is a kshism that has been
allowed to leak into POSIX and selects the behavior cd already implements.
Closes PR bin/42557 and also relevant to PR pkg/42168.
I suppose this should probably be pulled up to both -4 and -5...
