#67 \@input and "found no \bibdata command"

[Denis Porfiryev]

A project has several \include commands before \bibliography. Pybtex says "found no \bibdata command" after parsing first of included aux files.

Steps to reproduce:
1) unpack the attached archive
2) run "pybtex mywork"

Expected result: pybtex finds the \bibdata command.
Actual result: pybtex can't find the \bibdata command.
