It's a feature, as it makes filename entry more convenient, as you can
enter absolute filenames without erasing the existing path when entering
a filename.

Perhaps if Emacs were designed today, it might not do this pervasively,
and instead might just restrict this behavior to the filename prompting
functions (see, e.g. file-name-shadow-mode).

However, the current behavior has not been a problem in practice, as far
as I'm aware; the only place doubled slashes seem common is at the
beginning of a filename (because of naive DIR "/" REL_NAME concatention,
 with DIR == "/") , in which case the emacs behavior causes no change.


Fast, small, soon; pick any 2.
