Hi there!

I'd very much like to see some auto-parentheses indentation in Geany. I mean that this kind of indentation would be auto-generated on typing:
if (cond1 &&
    fun_call (param1,
              param2) &&
    cond3)
{
  another_call (param1,
                param2);
  /* and so on */
}

This includes:

• Indent new lines to match the position of the last opening parenthesis (lines 2, 3, 7);
• Automatically reduce indentation on closing parenthesis to fit the indentation of it's matching opening one (lines 4, 5, 8).

I'm trying to get this to work (attached WIP patch, which works but have caveats)[1], but I have a couple of problems (probably related to my little habit of Scintilla) and questions.
First, the problems:

1. How to know if a character is or not part of a comment, string or so? (e.g. should be interpreted as a syntactic element by itself) I need this to find the parenthesis -- and no, I can't do the same than brace_match() since I don't know the position of any of the parentheses.
2. Why brace_match() uses the character at (pos - 1) but the style at (pos)? This seems to be needed for brackets but breaks with parentheses (see comments in the WIP patch).

And now the unique question (not that urgent since the patch isn't ready): how to add this as part of the auto-indentation? (I mean, always enable it -- I don't think everybody will like --, add a new indent method, a new separated setting, or what?)

Thanks for your help!
