[Rd] tools::parseLatex() crashes on "\\verb{}"

[Antoine Fabri]

Do I understand correctly that we don't want Rd files to be valid latex ?
This seems odd to me.
I see that `tools::parse_Rd()` doesn't like `\verb!foo!` so maybe roxygen2
is actually doing the right thing (as opposed to just trying to) ?

`parse_Rd() ` is probably what I need indeed, for some reason I hadn't
found it, so that should fix my own issue here thanks a lot.
