Closes #12192: Document that mutating list methods do not return the instance (original patch by Mike Hoy).

I want to replace custom byte-compiling function with calls to
compileall before 3.3b1, but in the short term it’s good to have this
fixed.

Adapted from the distutils patch by Jeff Ramnani.  I tested with -B, -O
and -OO; test_util and test_mixin2to3 fail in -O mode because lib2to3
doesn’t support it.

Patch by Hallvard B Furuseth.

I tested this manually; it would be great to have buildbots using
installed Pythons, including Pythons configured with different prefix
and exec-prefix.
