For me this would fix the issue. I now applied something similar as
variable, but I would much prefer to see it be the default: That would
also solve the issue for a collegue of mine without me having to
explain him how the regexp works.

Regarding the need to translate other parts of the password prompt
(like "enter"), I think that those would be useful, but that the
current fix is already a huge improvement, so it should not be held
back by not being perfect right away.

Should the :version keyword of defcustom for
comint-password-prompt-regexp be set to 24.4, too?

Best wishes,

PS: I’m sorry that I only answer now. I lost track of the issue and
only now found it again when the bug finally disturbed me enough that
I decided to fix it myself (I have a local fix, but it is not as nice
as your fix). I now answered here again, because I saw no fix in the
current trunk.
