`\usage()` length

[olivroy]

Related to #1617, but different.

For functions with many arguments, roxygen2 places all the arguments on different lines.

However, since R 4.2, there is html support in help files, which means you can scroll horizontally to see arguments if needed.

My point is that you have to scroll down a lot to see documentation of arguments.

See example for tmap::tm_text().

When functions are documented together, this makes it even worse in my opinion.

I am also not convinced spaces between documented functions together are necessary, especially when there are more than 4-5 functions documented together.

See ?gert::git_commit

In help, it just reduces the amount of information you can see in a single screen

It would be good to have usage store 2-3 arguments on the same line whenever possible + reudce space when many functions are documented together
