Corrects `/-/.split("a-")` to return `["a", ""]` correctly instead of `["a"]`.
(`/-/` is shorthand for `Regex::new("-").unwrap()`.)
This adds tests for both `split()` and `splitn()` covering a variety of
edge cases. One test is commented out because it is failing due to #521.
A future commit will fix it.
Note that the `split2` and `split3` tests were passing incorrectly
before this change. I have fixed them to expect the correct values.
Corrects `/-/.splitn("a", 2)` to return `["a"]` correctly instead of
`["a", ""]`. (`/-/` is shorthand for `Regex::new("-").unwrap()`.)

/-/.split("a-")to return["a", ""]correctly instead of["a"]./-/.splitn("a", 2)to return["a"]correctly instead of["a", ""].Note that a couple of existing tests (
split2andsplit3) were passing incorrectly before these changes.I’m using
/-/as a short hand forRegex::new("-").unwrap(). It seems clear enough, but then I’ve written a lot of code in languages with regex literals.This supersedes PR #606 which attempted to fix #521.
I disclaim ownership of these changes. They are owned by whoever owns the bulk of the rest of the code. (I am not a lawyer, but I’ll head them off at the pass if I can.)
