Thanks for checking.  These files are identical, and the error is
preventing tramp--with-startup from getting defined during autoload
generation, so autoloaded calls to it just get inlined as-is in
tramp-loaddefs.el.  If it were working as intended, most of those would
be replaced by `add-hook'.

Gerd, do you mind reverting e9800cabffa and seeing what if anything
changes (from a clean start)?  Probably nothing.

BTW, Stefan and Michael, I see that tramp actually autoloads more
complicated forms using `tramp--with-startup', e.g.:

 (when (featurep 'dbusbind)
   (tramp--with-startup ...))

which means the macro definition still needs to be included in the
autoload file as well.  For consistency, maybe it makes the best sense
NOT to delcare autoload-macro expand in tramp--with-startup.  Thoughts?
