Thank you for your contributions.  I expect them to be reviewed soon,
but let me point out that the patches you are sending (in this and
other bug reports) have 2 problems which will make their application
harder than necessary:

  . the whitespace is converted to 0x00a0 NBSP characters, which do
    not exist in the original sources
  . the patches lack commit log messages, in the format described in
    the file CONTRIBUTE in the top-level directory of the Emacs
    sources

It is best to generate your patches using "git format-patch" and then
send them as an attachment, I think this will solve these problems,
assuming that you commit locally with the appropriate log message as
described in CONTRIBUTE.

Thanks again for your interest in Emacs.
