Renumber copyright clause 4

2017-02-28T23:42:47Z

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

sh: Fix duplicate prototypes for builtins.

2011-06-13T21:03:27Z

Have mkbuiltins write the prototypes for the *cmd functions to builtins.h instead of builtins.c and include builtins.h in more .c files instead of duplicating prototypes for *cmd functions in other headers.

sh: On startup of the shell, use PWD from the environment if it is valid.

2010-04-17T14:35:46Z

Unset PWD if it is incorrect and no value for it can be determined. This preserves the logical current directory across shell invocations. Example (assuming /home is a symlink): $ cd $ pwd /home/foo $ sh $ pwd /home/foo Formerly the second pwd would show the physical path (symlinks resolved).

Remove clause 3 from the UCB licenses.

Don't blindly eliminate `..' and the previous pathname component.

Make sh(1) a little braver in the face of adversity. sh(1)

now handles the getpwd() init problem the same way as bash and ksh do. Also while I was in here, I cleaned up the format a little, removed some unnnecessary #if SYMLINKS cruft, and changed the pwd builtin to use getcwd(3) as Joerg suggested.
