src/document.c: document_open_file_full()
But editor_create() and editor_destroy() seems more appropriate. I'd
say the very beginning would be to retrieve the current folding state
of an editor before it is destroyed (editor_destroy()). Then think
about a reasonable format to save this state to the config file and how
to reload and apply these information on next startup.
Also think of problems like how to handle the case when the file was
changed externally between two Geany sessions and so the saved folding
information became partly or completely invalid because the file
content changed.

It's all in src/editor.c where your new code also should go.

These are rather trivial and can be delayed until any initial code is
existent and working

Hmm, maybe this could work by implementing an own lexer in Geany and
use SCLEX_CONTAINER to tell Scintilla that Geany does handle it. But
this would require someone would write that code and define what's
useful to create fold points for no known format, i.e. whether to use
blank lines, indentation, a mix of those, something else, ...

Because it works here. And I just started Ubuntu 8.10 Live-CD in a VM,
installed Geany 0.16 from getdeb.net in this VM and tried it and it
worked. No idea what's different to your system except that you are
still using Geany 0.15, I would have tested this as well but couldn't
find any packages for 8.10 and I don't have the time to compile it
first, sorry.
If you or anyone can provide detailed information when and why it
doesn't work or even a fix, that'd be nice.

Regards,
Enrico
