When I use emacs python-mode, if the last character of a line is an open parenthesis it indents the next line just one step in from the indentation of the previous line.
call_some_function(
some_very_long_argument_that_I_want_to_put_on_its_own_line)
I like that. Now in ecmascript-mode (which I am using for actionscript 3), it always indents to the level of the previous parenthesis.
call_some_function(
this_is_not_really_saving_me_any_horizontal_space);
How can I make ecmascript-mode indent like python-mode in this respect?
