Ah, indeed.  The indenting change is needed to make Github parse the rst
correctly.  Feel free to remove the indenting changes and I'll send a
follow-up patch doing just that.

The current mbed TLS builds already reject legacy crypto (except the
fedora packaged build, apparently).  With this patch users have the
ability to use legacy stuff again, but I would prefer to not go any
further than that.  I think we should encourage people to drop the
legacy.  Just like the browser vendors are doing.

And for Fedora, they chose to experience intense pain when they chose to
go for OpenSSL 1.1 this fast, that's their problem I guess...  If they
want to be that cutting edge, they should also stop using legacy crypto.
 And otherwise, it will be a simple patch in the fedora packaging.
