This text would have made a very good introductory part of the commit message, but since it is after the three-dash separator, it is ignored.

The above two would be much better beginning of the log message for this change modulo a few nits. - We first explain what the current system does in the present tense. "Currently, " at the beginning is a pure noise. - And we point out what may be lacking (which you did a very good job in the second paragraph). - And finally, we write in imperative mood to give an order to the codebase to "become like so." or an order to the patch monkey to "make the codebase like so." As the last paragraph to follow the two paragraphs, something like Allow the selectors to begin with these special characters. would be sufficient. > - "^[_a-z0-9].*$", > + "^(([_a-z0-9]|[:[@.#][_a-z0-9]).*)$", As we seem to allow ? (i.e. zero or one) in the patterns, it probably makes it easier to read to spell the above like this instead? - "^[_a-z0-9].*$", + "^[:[@.#]?[_a-z0-9].*$"
