Patch removes the single-arg delDocs Term/Query variants. Everything compiles and tests pass. I'll sun jdocs tests too, though eclipse showed no additional errors about referencing those methods.
Do you think it's OK to backport to 4x? The only concern I have is if apps will upgrade to e.g. 4.9 by only dropping the 4.9 jar, not compiling their code as well. I don't know if people still do that though ... . Anyway, if we want to keep that, we can deprecate them in 4x.
