filemerge: be more strict when detecting conflict markers, add `|` markers
I received a user complaint about detecting a line that contained 78 `=`
followed by `*/` as a conflict marker. We'll never generate that, we generate 7
identical characters and either the end of the line, or a space. Let's be
explicit about detecting exactly what we produce to reduce the chances of a
false positive.
While we're here, add `|||||||` as a detected conflict marker (generated with
the `keep-merge3` style conflicts).
