[PATCH] Git/WinGit: Add default textconv for .dot

[PATCH] Git/WinGit: Add default textconv for .dot

As suggested by Consul on the list:

    Is it possible to make the antiword handling Word templates (*.dot)
    as well as documents (*.doc) by default?

    It works fine, if I add

    [diff "antiword"]
            textconv = antiword -f

    into the config file and

    *.dot diff=antiword

    into the attributes file, but this is repository specific.
    Can we make this behavior default?
