Correction: (almost) all buffers set a new value for
default-directory.  It is not easy to find buffers that don't, if they
at all exist.

Dired asks for the directory to edit.  If you go to Dired from
*scratch*, and if you accept the default without changing it, you will
indeed get the listing of the directory where Emacs started.  But I
fail to see how this is related to the OP, whose problem was to find
the correct speller on PATH.  And even in the above case, the
directory where you run Dired is explicitly shown in the prompt, so
the user should see it and understand what she is doing.

And my answer to the OP is that the value of "Start in" hardly
matters, although setting to something other than the directory of
another Emacs version definitely cannot do any harm.
