:swapname prints different string at different occasions

[GoogleCodeExporter]

What steps will reproduce the problem?

1. % vim -u NONE -U NONE --noplugin
2. :edit a_file.txt
3. :swapname           -> prints ".a_file.txt.swp"
4. :q!
5. % vim -u NONE -U NONE --noplugin a_file.txt
6. :swapname           -> prints "/home/user/.a_file.txt.swp"


What is the expected output? What do you see instead?

Prints the path of the swapfile as relative or absolute path, depending on when 
I called the command. Since I use the output in a script, it would be nice if 
the output would be consistent.

What version of the product are you using? On what operating system?

Both Vim 7.2 and Vim 7.4 on Linux.

You could write a custom script, something like this:

:command! Swapname :redir =>a|exe ':sil swapname'|redir end |let a=a[1:]|echo 
fnamemodify(a, ':p')

Alternatively, I'll attach a patch here. But until this is merged, use a script 
like this one.

Thanks for the patch and the workaround, but ... the patch doesn't fix the 
problem for me. I applied it, but the behavior is the same as before.
After all, you can easily work around it so it's not a big deal.
