It happens in many cases; when the editor is created, setting the
document indent type or width, when the preferences dialog is accepted,
when a new document is opened, when the filetype is changed, when a
document is cloned, and more that I'm too lazy to track down.
So it sounds like you probably need to do it some way to keep forcing
the setting if you don't want to modify Geany's code. Maybe in a
"editor-notify" signal handler in your script just call
SCI_SETBACKSPACEUNINDENTS at the top so it fires on every Scintilla
notification. It just sets a boolean flag inside Scintilla from what I
see, so I doubt the overhead would be too great for a one-off script.
P.S.: Here's a diagram that shows all the ways editor_set_indent - the
function that hardcodes the Scintilla setting - can be called from
inside Geany: http://www.pasteall.org/pic/show.php?id=59192
