get_maintainer.pl: unexpected behaviour for path/to//file

[Emil Velikov]

Hi Joe,

Recently I've noticed that get_maintainer behaves differently if there
is a double, sequential, forward slash in the path.

AFAICT there should be no distinction between the two. Or at least many
existing applications and scripts consider them one and the same.

I've tried fixing this, although my perl isn't quite up-to scratch.
Is this some weird bug or some intended feature?

Thanks
Emil
