fixed:generator method of class autocomplete causes star(*) to be add…

[limerickgds]

i add a onEnterRule rule that will only execute if the text above the this line matches /** or *.
but i don't think this is a good solution.

@alexandrudima / @rebornix Can you please take a look at this

[limerickgds]

@mjbvz @misolori @aeschli How long do I have to wait?

[aeschli]

@alexandrudima and @rebornix have the final word here, but looking at the previous line looks fishy to me. For other language configurations we can already express where the rule applies:

	"autoClosingPairs": [
		{ "open": "/*", "close": "*/", "notIn": ["string"] },
		{ "open": "\"", "close": "\"", "notIn": ["string", "comment"] },
	]

See https://github.com/Microsoft/vscode/blob/7c03ce156505cca6c60bd5afd9b2f33f25ec64ad/src/vs/editor/common/modes/languageConfiguration.ts#L177.

Ideally, we can add the same for OnEnterRule

@aeschli do you need i change this PR ？

[alexdima]

I personally kind of like it that the implemention of onEnterRules is kept tokenization agnostic and I think the new rule (oneLineAboveText) is in the same spirit with my original implemention (i.e. similar to beforeText and afterText).

@limerickgds Thank you !
