bug#735: Bug in etags ".." code

[Francesco Potorti`]

Ok, it has been quite some time since you reported this bug, but at last
I managed to look at it during my vacations...

Thank you for the patch for collapsing multiple consecutive slashes in
file names.  I generalised it by canonicalising all file names as soon
as they are read into etags.  I just installed the change into the
trunk.

I did not install it into the pretest branch yet.
Since this is a bug, it probably should go into the pretest branch too.

What do people think?  I am unsure whether this is serious enough to
grant a patch to the pretest branch,

P.S.
Please put me in Cc, as I discovered that I am no more subscribed to the
list, and a new subscription is in progress.
