5678a13f1b Re-introduce some code from 1.14 (with modifications) to make the 
shell's idea of the current working directory match reality when
symlinks (or anything else we can't stat) are traversed with the
cd command. However, this does not print out the cwd after cd
traverses symlinks, as it used to, though the capability is still
there should one want to use it.

340077b543 - fix parsing bug reported by mycroft: ! was only recognized in the beginning 
of pipelines. Now we are recognizing it everywhere like ksh, so:

	! if [ a = b ]; then ! echo c && ! true; else ! echo d; fi

  works.
