Good for you. (symbol-function 'help-for-help-internal) (h-f-h-i being what
help eventually resolves to) gives me a compiled function with a nil
documentation slot; help.elc has (defalias 'help-for-help-internal ...) with
a compiled function and what seems to be the correct lazy doc reference. The
DOC file seems correct, with an entry \x1fFhelp-for-help-internal
Help command.\x1f
But (documentation #'custom-declare-variable-early) and (documentation
#'when) both give nil for me, and the same seems to be true for all the
dumped compiled functions with docstrings. I don’t know why that is, and I
don’t especially care to debug it right now, but this binary is what Cygwin
installed, I’m certain I’m not the only one affected.
