Please note, Geany isn't Vim, IDEA, Eclipse or any other editor.

That binding is undocumented so it could do anything, including eating your shorts. And it does not have a menu entry. And in fact it does `join_paragraph()` so its also misnamed. So in general that entry should be deleted. Especially as joining a paragraph has been superseded by reflow lines.

After its deleted someone could replace it with some other functionality, like simple join lines, and this time with a menu entry as well. Just needs somebody to make a pull request.

@LarsGit223 on further consideration I guess join paragraph is useful for some HTMLists who have their paragraphs on one line and similar use-cases and reflow doesn't do the same thing.

IRC (without checking) reflow uses the `join_paragraph()` code so its not going to be removable even if it was exposed from line operations.

So since it already exists in Geany I guess that although "Join Lines" is technically correct it does not actually describe which lines. So the keybinding should to renamed to "Join Paragraph", added to the Edit menu (eg next to reflow), and documented rather than removal.

One day "somebody" will go through the keybindables and find all those not in the menus and add them so they are discoverable, but thats a separate issue.
