js-ts-mode and js-mode behave differently when calling
default-indent-new-line (M-j) within a multiline comment.

Observed behavior:
  - in js-mode, M-j calls c-indent-new-comment-line, which correctly
inserts a newline, indented to the correct column and prefixed with '*'
  - in js-ts-mode, M-j calls comment-indent-new-line, which inserts an
indented newline without the prefix.

Expected behavior:
Block comments should be handled the same in both modes.

Steps to reproduce:
1. emacs -Q
2. open a scratch buffer in js-ts-mode and enter text (without quotes) "/*"
3. press M-j
4. observe newline is created without star prefix

Follow the same steps in js-mode to observe the desired behavior.

I suppose following in js-mode's footsteps and reusing this part of CC 
Mode is the obvious solution.

I haven't looked at the implementation closely enough to suggest 
something else, but it'd of course be nice to be able to provide a 
self-contained, shorter re-implementation instead.

Sounds good. I wasn’t aware of this command before. Let me add it to c-ts-common.el.

Ping!  Yuan, can we make some progress here?

I looked at the implementation of c-indent-new-comment-line, it’s 178 lines of complicated control flow, handling all sorts of edge cases that I don’t understand. Sadly it’s pretty keeping coupled with the whole cc framework, so it’ll be pretty hard to take it out and reuse for c-ts-common.el.

So I added a new function c-ts-common-comment-indent-new-line. It’s probably nothing compare to c-indent-new-comment-line’s capabilities, but it can at least handle the usual cases that I can think of: indenting after //, after /*, after * inside a block comment, and after | inside a block comment.

For more advanced use-cases, we can wait until someone asks for them.

Evan, if you pull the latest master, M-j should now just work for js-ts-mode.
