Thanks, fixed on the emacs-25 branch.

Thanks, however I'm still not quite sure about the meaning.
"ASK non-nil means ask the user whether to keep each unmodified buffer, unless KEEP-VARIANTS is non-nil, in which case buffers are killed unconditionally."
So if ASK = nil, KEEP-VARIANTS = nil: kill buffers, don't ask about any buffer
ASK = (nil or non-nil), KEEP-VARIANTS = non-nil: don't kill any buffer, don't ask
ASK = non-nil, KEEP-VARIANTS = nil: ask about each buffer

If that's the case, shouldn't the documentation rather be something like:
"If KEEP-VARIANTS is non-nil, only indirect buffers are killed [what does that mean for the user?], and ASK is ignored. Otherwise, if ASK is non-nil, ask the user for each unmodified buffer whether it should be killed. Otherwise (both ASK and KEEP-VARIANTS) are nil, all unmodified buffers are killed without confirmation."
