Drag and drop should not escape file paths in alt mode

[delthas]

Hi,

Currently dragging a file onto ghostty will insert an escaped file path (on both Linux and MacOS).

However, while this is useful when inserting paths into a shell, it is not standard expected behavior when pasting into an alt mode application, like vim. For example, if you drop a file called my document.jpg, you'd expect it to be inserted as is into the editor, without changing to my\ document.jpg

On the 2 other Wayland terminals I checked, the behavior was to disable escaping file paths when alt-mode was enabled:

• foot prevents quoting files on the alt screen (issue) (source)
• Kitty prevents quoting files when not "at the prompt", meaning either in alt screen or when the cursor is not at the row of a prompt (source) (source)

A concrete consequence is that in my TUI IM client, when receiving a DnD file, I treat it as "unescaped", but I get some backslashes and then I can't read the file.

I suggest adding, like foot and Kitty, no quoting when in alt mode.
