pwd() reflects the actual directory and not symbolic link
I've noticed for years that whenever a directory is specified in Octave,
be it in the File Browser directory showing the files, or be it messages
that dbFUNC displays about the current line position, etc. that it is
always the real directory. I never thought much about it, but I'm now
wondering why not make an attempt to reflect the "working directory"
that the user launches from or selects in the navigating file dialogs?
From the user's perspective, I'm thinking s/he'd like to see the "link"
version of the directories.
