I note that you're using Evolution. When posting content that's sensitive to wrapping (e.g. a long URL) it's better to use Preformatted mode (see the drop-down menu just above the edit pane), even if just for that section, like this:
A very very very very very very bery very very very very very very very very very very very very very very long line.
And I reselected that line as preformatted when replying...
I notice that Evolution will often mangle presformatted line while composing and editing messages, especially if you've saved a draft and gone back to it. Toggling the message format into HTML then back to plain text usually fixes it.
