key lower()

[Former user]

entry key should be untouched. now it makes it lowercase. f.e: @​article{KEY, ... }

should output bibitem{KEY} and not bibitem{key}

BibTeX converts entry keys to lowercase, so does Pybtex.

OK, I was wrong - BibTeX outputs the key exactly as it is specified in citation{} in .aux file. This is now fixed in trunk.
