Yes -- I don't think there is a use case for sticky or setuid bits on log
files, even allowing execute is questionable.

Aha, that would ensure that the execute bit is not specified. Works for me.
The 0699 and other invalid octal values are caught by strtol()

Converted to umask()

I've now (re)added the show_log_file_mode(). It used to be there, but then
at some point I decided to display the value "as-is".

While going through it, I moved the _setmode() call for win32 to logfile_open().
