Here's what I have so far:

  http://hg.savannah.gnu.org/hgweb/octave/rev/e0bcd17ac070

I pushed it even though it is not complete so that it would be easier to 
test.  It only adds code and doesn't modify an existing behavior.

Currently, this new indent feature is not connected to any keyboard 
shortcut yet and is only accessible from the Edit -> Format menu in the 
editor.  What keybinding should it use by default?

I'm sure there is a lot of room for improvement since this is very 
simplistic.  You can easily fool it by having multiple block (begin or 
end) keywords on a single line.  Only the first will be noticed, so 
indentation will probably not be correct.  It does not attempt to detect 
mismatched begin/end pairs (for matched by endif, for example).  But it 
does appear to work correctly for me with well-formed code.  It will 
work on a single line (where the cursor is) or on a block of selected text.

It probably should be limited to Octave code since it uses regexps that 
are for Octave syntax, not other languages.  I'm not sure how the editor 
works for different types of files.

Comments, help, and suggestions welcome.
