are equivalent to a single slash, except at the head of the path,
where a double slash may have a different meaning. (On the Apollo
machines of old, running domain/os, a leading double slash indicated
the "network root", so you could specify //hostname/foo/bar to get
/foo/bar on the host named hostname. It seems they took the Sun slogan
"the network is the computer" to its logical conclusion.)
Miles Bader gave a different explanation for emacs's behaviour. It
seems odd to me that an interactive feature (a good one, too) should
influence how path names are interpreted in code, however.
PS. On those old Apollos, we changed root's home directory from / to
/. in order to avoid being surprised by programs that constructed
paths as $HOME/foo/bar.
