When publishing files using org-babel-tangle-publish, if the :tangle
header argument is given to a source block, and if org-babel-tangle-publish
is called from a directory other than the directory in which the source
file (that is, the file being tangled) exists, then org-babel-tangle-publish
fails in the copy-file step.

This happens because org-babel-tangle returns the file name (that is,
the basename only) mentioned in the :tangle header argument, and
org-babel-tangle-publish tries to copy that unqualified basename
instead of the absolute path to the file.

My emacs configuration follows. I used the minimal configuration given in
the Feedback section of the org mode manual. The backtrace for the error is
also attached.

Thanks,
Arun Isaac.
