methods are not allowed for skipped fields when using multi-line doc comments

[DianaNites]

Title. Structopt 0.3.0 errors out with methods are not allowed for skipped fields if skipped fields have doc comments, but only multi-line ones.

Repro:

#[derive(StructOpt)]
struct Example {
    /// This does an internal thing.
    /// Run-on sentence explanation.
    #[structopt(skip)]
    works: String,

    /// This does another internal thing.
    ///
    /// # IMPORTANT NOTE
    #[structopt(skip)]
    fails: String,
}

Should also exists in 0.2, that's because we generate a long_help when we detect a paragraph.

Perhaps we need to completely separate auto-generated stuff from explicitly requested one.

Changelog says skip was introduced in 0.3
