if core.filemode is true, Git for Windows could:
a) Behave as today, report changed files (filemode)
b) Give warning to the user (and report changed filemode)
c) Error out, saying misconfigured worktree
d) use core.filemode = false anyway.
e) Give a warning and use core.filemode = false anyway.

At the moment I tend for c), as it makes it clear what is going wrong,
what do you think ?

[skip ignorecase for a second]
