Most [1] other editors call this command "revert" and they clear the
edit history, that makes sense, they are "reverting" the buffer to its
initial state.  So they have prompts.

Geany is just reloading the file contents as another editing action.

Since Geany is clearly ahead of the pack here maybe we *should* have a a dialog:

  Did you know that reloading is just another editing action and can
be undone like all the rest?

  It is not like other editors crappy destructive "revert" commands.

[1]: "Most" on my system consists of gedit and emacs, but I had a
