This is because when you haven=E2=80=99t typed out the complete =
statement, the
parser couldn=E2=80=99t naturally don=E2=80=99t have the complete =
statement in the parse
tree, so the indent rules didn=E2=80=99t match. Once you completed the
statement, everything works as intended. We would need to add some
clever heuristics to match even when the parse tree is incomplete.

I=E2=80=99ll try to do it when I found some time, thought the priority =
would be
lower than other stuff.

The content doesn't seem to indent on newline after the user press
<Return> as in c-mode. And the user requires to press TAB explicitly
for this happen (and indentation happens only on non empty content).

Say for example, for the following code, if I press <Return> (| is the 
point)

if (success)|

I get:

if (success)
|

but I expect the following (with gnu style and 2 space indentation):

if (success)
   |


This is very much broken in do-while loops:

Say if I do:

do
{
}

and do TAB (after selecting the whole code), indentation doesn't happen
(with gnu style), but it seems to happen right once I complete writing
while(0); (or so). (Or is this a different bug?)
