I have sentence-end-double-space customized to nil, and a find-file hook
that changes it according to the contents of the buffer. I changed this
hook function so that it only ever sets sentence-end-double-space, and
never clears it.

After this, I find that the variable is correctly overridden by
.dir-locals.el in some magit buffers, but not in COMMIT_EDITMSG buffers
(which are in text-mode). I don't know whether this is something to do with
commit buffers being invoked via emacsclient.

Anyway, I ensured the spacing manually, and filed a magit bug. I thought
this problem might be of interest to other Emacs maintainers, as magit
seems to be (rightfully!) quite popular.
