How do I double-indent if continuations?

[mid-kid]

My personal style does something like this:

if (thing == VERY_LONG_ENUM_NAME_THING1 ||
        thing == VERY_LONG_ENUM_NAME_THING2) {
    do_some_thing();
}
if (some_long_func_call(param1, param2,
        param3, param4)) {
    do_some_thing();
}

I do this to distinguish the contents of the if statement from the rest of the block, without having to add an extra line in-between. I've been messing with the indent_sparen_extra option, and it doesn't seem to do anything. The default configuration always removes the extra indent.

Appaerently the indent_func_call_param = true option was overriding this and making it hard to get right, and indent_sparen_extra doesn't work unless indent_continue is nonzero
The following works, and does exactly what I want above:

indent_columns = 4
indent_continue = -4
indent_sparen_extra = 4
indent_func_call_param = false

Please, provide an example which shows your problem.

The problem was not being able to get uncrustify to indent code in exactly the way shown in the OP, either always indenting 1 tab from the if, or modifying indentation depending on brace depth. I always indent if continuations with 2 tabs regardless of brace depth.
Most configurations (including the default configuration) would reindent it to something else, and the toggles to achieve this, as found in the accepted answer, weren't exactly obvious.
