Plugin mistakenly identifies files with the same name in different directories as identical

I tried working around this with set titlestring=%{expand(\"%:p:h\")} in my vimrc, but this did not solve the issue.

Same problem.

I got it working with:

set titlestring=vi\:\ %-25.55F\ %a%r%m titlelen=70

Good enough for me.

Seems like any solution for this is going to need to use readlink -f FILENAME (on Linux) to handle this case correctly. Consider the following:

gvim ../foo
cd ..
gvim foo

Here we have two different names given to gvim, but for the same file. Using readlink -f to get the canonical path will ensure the equality test is accurate. Granted $SUBJECT is about two different files and I'm describing two references to the same file, but I believe it still applies and simplifies how the fix should work.

It appears from testing that vim's fnamemodify function does yield the canonical path when given the :p option. So that makes a good platform-agnostic solution here.
