We could consider renaming hl-line-mode to highlight-line-mode, I guess?
Anybody have any opinions?

But I don't think completing hl to highlight-line-mode would make much
sense, even if it was possible, because nobody would be typing `M-x hl
TAB' in the first place without knowing that the mode was called
`hl-line-mode'.
