So it makes sense to preserve the original contents of the help buffer
in other uses too.

Now I see a new argument `buf' was added to `describe-char' in CVS.
This doesn't work even for normal uses of the help buffer.  Clicking
on any link in the help buffer created by `describe-char' and going
back produces nonsense, because it tries to restore the old contents
based on the old position in the new contents of the help buffer.

OTOH, I've tested that saving the whole old contents as a string
works flawlessly in the help buffer for all links.  Are there reasons
not to use this solution?
