* Correct indentation, using correct (I hope) indentation code
Note that part of the code, in formatting.ts, is cloned but should be
extracted to a function instead.
* Remove some possibly-superfluous code
But I see 4 failures with whitespace, so perhaps not.
* Restrict indentation change to avoid breaking baselines
The indentation code is very complex so I'm just going to avoid breaking
our single-line tests for now, plus add a simple jsdoc test to show that
multiline jsdoc indentation isn't destroyed in the common case.
* Switched over to construction for @return/@type
Still doesn't merge correctly though
* Add @return tags to emitter
* Merge multiple jsdocs
(not for @param yet)
* Merge multiple jsdoc for parameters too
* Emit more jsdoc tags
Not all of them; I got cold feet since I'll have to write tests for
them. I'll do that tomorrow.
* Many fixes to JSDoc emit
And single tests (at least) for all tags
* Cleanup in textChanges.ts
* Cleanup in formatting.ts
(Plus a little more in textChanges.ts)
* Cleanup in inferFromUsage.ts
* Fix minor omissions
* Separate merged top-level JSDoc comments with \n
instead of space.
* Don't delete intrusive non-jsdoc comments
* Cleanup from PR comments
1. Refactor emit code into smaller functions.
2. Preceding-whitespace utility is slightly easier to use.
3. Better casts and types in inferFromUsage make it easier to read.
* Fix bogus newline
* Use @andy-ms' cleanup annotateJSDocParameters
