Bug with $cwd in 4.2BSD csh

[chris]

The following changes to 'sh.dir.c' will take care of the problem:

1) in dfollow(),
    1.1) add this declaration:
	char *realdname();
    1.2) before 'dcanon(cp);' insert:
	cp = realdname(cp);

2) then add this routine:

char *
realdname(d)
char *d;
{
	struct stat st;
	char *getwd();
	char path[BUFSIZ];

	lstat(d, &st);
	if((st.st_mode & S_IFMT) != S_IFLNK)
		return(d);
	printd = 1;
	return(savestr(getwd(path)));
}
