[matplotlib-devel] A small improvement to plot directive

[Fernando P. <fpe...@gm...>]

Hi all,

would anyone mind if I commit the attached patch?

It's 100% backwards compatible and allows for turning plot directive
errors into fatal exceptions easily, so one can make sure that docs
either build correctly or not at all.  This is useful for having
examples be a kind of test suite, in addition to any unit tests a
codebase may have.

Thanks,

f
