Hi @sbelak; and @milkypostman and other MELPA maintainers,
I noticed that hl-sentence and sentence-highlight are essentially the same. In fact, both admit they are based on code from http://www.emacswiki.org/emacs/SentenceHighlight. Several of the functions are sexp-for-sexp identical. hl-sentence is more idiomatic as a package, as it uses define-minor-mode, while sentence-highlight manually adds itself to the minor-modealist.
It seems unnecessarily confusing to have both of these packages in MELPA. I suppose it would inconvenience existing users of one or the other package to have it removed, but for potential new users, it is confusing to have both, as, without examining the source, it's unclear which is preferable.
Not a very important or urgent issue, but I thought I'd bring it to your collective attention.
Thanks for your work.
To save you some clicking: hl-sentence and sentence-highlight.
I think we should settle on hl-sentence. I have submitted some cleanup and fixes to make that more appealing.
We can add :old-names (sentence-highlight) to the hl-sentence recipe to help users of the former.
I'm totally fine with retiring sentence-highlight, the more idiomatic solution, the better.
