Remove trailing newlines in body

[xethos84]

Whenever a message is sent, a newline is appended. This breaks some functions, like interacting with Bridge bots for things like Google Chat. The bot expects the body to exactly match command, and fails when the body is command\n. I've noticed the newline is also appended to the body of my regular messages, not just single-word ones (though it doesn't break messages in rooms as far as I've noticed).

Hopefully messages can be sent without the extraneous \n being added to every single one.

I'm on 0.0.8 and every message I send has an additional line in the end. I guess it's relevant to this issue?

I'm still having this problem, installed with cargo and on version 0.0.9. Contacts I talk to say my messages have an extra newline on the end.

It seems like the newline is added by the conversion to markdown, so you'd need to trim the result of that, not its input:

use comrak::{markdown_to_html, Options};
assert_eq!(markdown_to_html("Hello, **世界**!", &Options::default()),
           "<p>Hello, <strong>世界</strong>!</p>\n");
