gnulib-tool --lgpl exception for self tests?

[Simon Josefsson]

I'm using gnulib-tool --lgpl in some projects.  All of the *-tests
modules that I wrote recently are GPL.  There isn't really a need for
these self tests to be available under LGPL, but gnulib-tool complain
because I used --lgpl.  I think it would be fine to include GPL self
tests in a LGPL project, so I want gnulib-tool to deal with this
scenario.

Should there be a "gnulib-tool --lgpl --gpl-is-fine-for-tests" mode?

That mode would reject GPL modules, except for self test modules.  It
would change the license headers for normal modules from GPL to LGPL,
but not on self test modules.

If we don't agree on this, I'll re-license all of my self tests to
LGPL so I can include them in GNU SASL.

Thanks.
