C-h f car [RET] => "Wrong type argument: stringp, t"
C-h v * [RET] => "Wrong type argument: stringp, t"

The error happens in (with-current-buffer standard-output ...) because
standard-output is not bound to buffer *Help*, like it was before.

I can't reproduce that.  Does it help when you remake the autoloads?
`with-output-to-temp-buffer' had the argument (help-buffer) here which
should evaluate to *Help*.  Can you understand why it doesn't in your
case?

Now, this is weird. The bug was present after several rounds of "make
cvs-update" (which does the recompile and autoload targets, among
other things) followed by "make install".

However, it has disappeared after manually recompiling help-fns.el...

    C-h f car [RET] => "Wrong type argument: stringp, t"

I got that, but then I rebuilt Emacs using `make clean' and `make
bootstrap' (which I try to avoid since it takes me so long) and now my
`emacs -Q -D' works fine.  Now, I get the proper result for `car'.

I never do that but if it recompiles before making the autoloads,
wouldn't that fail?  `help-buffer' is in help-mode.el but was not
autoloaded before, probably because only `with-output-to-temp-buffer'
needed it (I fail to understand how that worked).  I'm reluctant to put
any requires in help.el (it used to require `view-mode' once) to avoid
recursing.  If you have any suggestions ...

Does that mean you still see it with `describe-char' or `describe-face'?
Or did you recompile them too?

In fact `make bootstrap' is what I tested before checking this in - it
takes more than an hour on my system.  Sorry for the inconvenience.

Aha.

I still saw it with describe-key. At that point I bootstrapped ;)
