highlight linenr without enabling signs?

[JeanMertz]

This request is similar to #741, except that I'd like to use line number highlighting (g:ale_sign_highlight_linenrs), but not have Ale touch the signcolumn(s).

The reason being:

1. highlighting an entire line is too obtrusive
2. I'd like to keep the sign columns reserved for other plugins, and use line number coloring for Ale specifically.

I can create a PR when I find some time, but wanted to make sure this is something you're willing to entertain.

[JeanMertz]

I should clarify: I can set g:ale_sign_error etc to '' and remove any highlighting, but I suspect that would still make ALE potentially override other signs being shown at that line.

However, thinking some more about this, I guess that plus setting g:ale_sign_offset to 0 might actually be enough to make this work?

I'll leave this open in case that's not true, or you'd like to make this a bit easier to use, but feel free to close this if what I propose is what you think is the best approach without changing Ale.

[JeanMertz]

Ah never mind, it's priority that I'd need to change, not offset (which is just an ID that has to be unique). So this would still require changes to Ale as far as I know, either allowing changing the priority of the signs, or supporting the original request.

You might be able to implement this by only setting text= if the sign text is !empty.

@JeanMertz support for sign-priority was added recently to ALE (see #2786 ). By setting g:ale_sign_priority to a low value (< 10) you can ensure ALE signs will be hid by other plugin signs.

Would be great if you can test this and close this issue.
