But what does

disk:A, dirstate:a

on a folding workspace mean?

One of:

1) user has deliberately renamed a to A with fs operations
and not yet told Mercurial about it (hg mv --after).
2) same as 1), but it was unintentional.

Since Mercurial doesn't yet have psychic powers, it
treats 2) as 1) and should report the situation on hg sta.

That means if the user did 1) or 2) plus changed the file
content, Mercurial should refuse to hg ci.

Correct?
