Hi all,
is it the normal behavior of directory-files to use default-directory
when it is called with empty string or is it a bug?
actually with emacs -Q:
(directory-files "")
return the content of default-directory.

That is the normal behviour of every file related function. It is
basically what expand-file-name defines.

Indeed, although I don't think it's documented, and code had probably
better not rely on it.

Ok i see, thank you Stefan and Andreas, maybe that should be documented, for
all file related functions.

I prefer to keep features which are accidental undocumented, unless we
really consider them as good features (even if we bumped into them by
accident), in which case they can be documented and their use can
be blessed.

Yes i understand, but it is not a good feature IMHO.
These kind of functions should return an error with empty string, as
empty string is not a valid path.
But maybe this "feature" is used somewhere?
