Not a fix for the original issue, but for what it's worth, I just added
more comprehensive documentation on how to view task signatures here:

http://www.yoctoproject.org/docs/2.2/ref-manual/ref-manual.html#usingpoky-viewing-task-variable-dependencies

Running bitbake-diffsigs instead of 'bitbake -S diffsigs' would be an
alternative.

I also had trouble getting 'bitbake -S diffsigs' and 'bitbake -S none'
to work as advertised. They write a file locked-sigs.inc too, which
seems to be undocumented. I relegated the bitbake -S documentation to
the end of the new section and kept it as it was before.

Cheers,
Ulf
