At this place, We can find a real file with suffixed filename (`fn')
that needs to be handled in a special way (e.g. a compressed 
one: "/a.elc.gz") while `filename' holds the requested 
filename without the suffix ("/a").

In this case, the file shouldn't be opened and the function (openp())
should not return the fd. It should return -2, and the calling 
function (load()) should call the corresponding handler in order
to load it.

It used to check whether there is a special handler by passing `filename'.
Such a test used not to give the expected result, since the handler
is applicable to the real (suffixed) found filename `fn'.

Loading libraries stored as compressed .elc-files used to be broken 
because of this: the corresponding load-handler (`jka-compr-load') 
used not be called, and the docstrings for the loaded functions
got corrupted when displayed.
