Ah yes indeed.

Avoiding the filemode check completely during reinit is ok with me
because it gave me wrong results.  I can't speak for the original
author of the code - if his intention was to do it explicitly as part
of "reinitialization".

[In the latter case personally I'd want to edit the config file by hand
in response to a message from git - and I certainly do not want git to
change the config file behind my back without informing me.]

Thanks again.
