Bug: Emacs mode indentation bug

The GNU Smalltalk mode for Emacs doesn't seem to like matching
brackets (and possibly parentheses) to be in different columns.

Example:

Object subclass: Foo [

                aMethod [
                                ^self
                ]

anotherMethod
             ^Try to type colon (':') here, and it prints the
             following error message and refuses to insert a colon.
forward-sexp: Scan error: "Unbalanced parentheses", 49, 41

49 and 41 seem to refer to the brackets around the body of #aMethod.

If I reformat the file like this...

Object subclass: Foo [

                aMethod
                                [
                                                ^self
                                ]

anotherMethod:

...it stops complaining and lets me type a colon.

I know the first way I had it formatted is valid, because I've seen
GNU Smalltalk packages formatted with the brackets in different
columns.

The thing I don't get is how this behaviour even exists, since,
presumably, some of the GST developers use Emacs, so how can I, a
total noob, have encountered this almost right away without any of the
developers noticing it?  I see either two possibilities: 1) My Emacs
installation or configuration is causing the bug to show up, or 2)
smalltalk-mode was not written for the devs, but for users.

Either way, can anyone help me?

Thanks,
Aidan

Erm, sorry.  Those examples again without tabs...

Object subclass: Foo [

    aMethod [
        ^self
    ]

                anotherMethod

----------------------------------------

Object subclass: Foo [

    aMethod
        [
            ^self
        ]

        anotherMethod:

You can also see that, even though it lets me type a colon,
#anotherMethod is intented further than #aMethod, when they should,
obviously, be indented the same level.

I think your changes didn't make it into 3.2.3.  So it is fixed with
your latest .el files?

This happens much more often than you'd think (and not just with
gst!).  That's why new users are as important as "mavens"!

Yeap :) And that is a good way to build good software.
Using the tool we are building is the best way to have it correctly.

Paolo  you can take the latest smalltalk-mode.el file in my git repository:
https://github.com/mathk/smalltalk.

I have revert the fix I have made for Nicolas because that was ugly
and it make things worst then it fix things. I will find an other
way to fix the bug.

Be aware that the latest revision contain also the find-tag function
(it have some bug but work for most of the case, I am fixing it bit by bit).
