Stop completions inside of comments

[nicholas-peterson]

Description

Often I'll be writing a comment using '///','//', or '(* .. *)' and want to enter a carriage return or tab. If company mode suggests a completion right as I'm doing this, it enters the completion rather than the desired keystroke. It strikes me as rare that someone would need the completion inside a comment, and wondered if it would help anyone else to simply not trigger completions inside comments?

Repro steps

• Open a .fsx file with a project and start entering a comment.
• Then place a space, or single character that would start a completion as the end of the line being entered. For instance ' ' or 'a'. This starts the completion menu from company mode.
• Then hit enter.

Expected behavior

Instead, the completion menu would never trigger because we're inside a comment block.

Actual behavior

The completion menu triggers, suggests a completion, and that keyword is entered rather than a carriage return.

Known workarounds

Cancelling company mode completion using C-g seems to work, just taxing to perpetually do on multi-line comments.

The current implementation changes the global company-minimum-prefix-length to 0which results in all company-backends kicking off.

This only happens inside strings and comments because the fsharp-completion backends only passes control to other backends when (point) is inside strings and comments.
