no, I meant 'extracklean'.

Another nit to fix, I guess.

That "almost" is there for a reason.

Not in this project, no.  maintainer-clean leaves some generated files

to a branch that has diverged significantly from the previous one is a
relatively rare use case, so removing those files would mean
unnecessarily longer builds.
