So what can we have it turn "--" into? An obvious answer is
em-dashes, but then you run into the problem of text encoding.
We could backslash escape them.

Well, if Markdown somehow magically protects you from generating
invalid XML comments containing "__", I don't see how it's any
more likely to make you write badly-formed comments elsewhere than
if Markdown simply does nothing about the problem, and it "just
works" anyway in all modern web browsers.
So here's my proposal for Markdown comments:
Ends with first instance of:
Between start and end, any run of N consecutive dash characters,
where N > 1, e.g.:
is replaced with a dash followed by N - 1 backslash-dash sequences:
And, before this dash-fixing takes place, any existing backslash-dash sequences would be turned into backslash-backslash-dash.
So, given this Markdown input:
<!-- -- \- -->
<!-- -\- \\- -->
