Please prepend a blank comment line for conformance with our style guides and consistency with C style comments.

Where is it stated in the style.mdoc.5?

I did some grepping of the man pages, and I do not see the empty comment line at the start of the man pages for most cases.

It has nothing to do with manpages. It is stated in the license guide and in style.9

Yes, no one listens to me, but it is wrong.

I do not see it in style.9 either.

the license shown in style.9 has a blank comment line. the actual source of style.9 has a blank line before it. the needs to look the same in every language. i do not understated how this is contestable at all or controversial about this or why someone would want to deviate.

waited

belongs

That's missing a word or two.

This is a somewhat awkward sentence, at least when rendered by man.

Its size is passed

signalling (a typo)

a semaphore

There is no blank comment line in style.9 C example, this is just a multiline C comment formatted properly.

In the style.9 itself, there is the blank line in the beginning only because you put it there, it serves no purpose. Git blame clearly shows that the 'failed experiment' of the addition of the '-' mark was performed, then instead if removing the .\"- line, it was replaced by .\". IOW there is no point.

Indeed, and ETIMEDOUT which is returned for timeout is somewhat special so I mentioned it.

The point is so that they are all formatted the same.

tag requires a width or the linter complains

There should not be periods if these are not sentences, but if they are sentences, the beginning should be capitalized. Also typo on signaled.
