For some reason most of the RST files use MAC `^M` instead
of UNIX `\n` newline characters.
This is problematic because e.g. git diff doesn't work with
MAC newlines by default and considers such files as one line,
giving meaningless results:

I ran the mac2unix tool to convert MAC to UNIX newlines
as suggested here:

Besides these RST files the GammaLib repo seems to be clean,
i.e. no other files changed when I ran mac2unix on them.
