[cc] switch should indent +2 for cases, not +4

[mtaran-google]

int main() {
  int i = 0;
  switch (i) {
  }
}

when pressing enter after the line with switch on it, the indent should be +2

Your indentation tests require regular statements inside of switch to be indented 4 spaces, and labels 2 spaces.

I see... right now it will unindent two spaces after the : is typed. That ends up working, but it'd be better if the indent was +2 from the beginning. It does appear that it's technically possible to put other statements before the initial label, but that is not actually useful for anything, so the statements between labels will always be +4 and the labels will be +2.

It's hard to know, in the indentation code, whether we are at the start of the block or after some label, and as you noticed, it'll correct itself anyway when you type a label, so I'd argue this isn't a huge problem and doesn't warrant extra kludges. Was also not part of the initial requirements.
