   That seems to corroborate my feeling that either there is a bug (on Windows)

What about the alternative docstring in the patch below?  That one
should describe the actual behavior or there _is_ a bug (on Windows).
I can install if desired.

To explain what _should_ happen and _does_ happen on GNU/Linux: I have
four files starting with cin: cinv.tex, cinv.tex~, cinv.aux and cinv.dvi.
All but one end in a string in completion-ignored-extensions.  If I do
`C-x C-f cin TAB', it completes to cinv.tex, ignoring the three other
ones.  But if I do `C-x C-f cin ?', I get a list of all four.  This
feature is meant to allow you to complete to what you _probably_ want
with less typing.  It is _not_ meant to prevent you from visiting
files that end in one of these suffixes.
