[clangd-dev] textDocument/onTypeFormatting and live indentation.

[Ilya Biryukov via clangd-dev]

The proposal looks promising, but why only reindent? Here are two useful
type-as-you-go heuristics that I've seen ('^' indicates cursor position
before and after adding a newline):

1. Reformatting braces.
before:
if (foo) {^}

after (note two newlines were added, so strictly speaking it's not just a
reindent):
if (foo) {
  ^
}

with a different brace formatting style:
if (foo)
{
  ^
}

2. Auto-typing comment markers.

before:
/// Comment line 1.^
/// Comment line 2.
int foo();

after:
/// Comment line 1.
/// ^
/// Comment line 2.

With a different comment type. Before:
/** Comment line 1. ^
  * Comment line 2.
  */

after:
/** Comment line 1.
  * ^
  * Comment line 2.
  */
