Doesn't lowercase small words

[q3cpma]

For example

$ echo 'Way Of The Dragon' | titlecase
Way Of The Dragon

Well that's embarrassing, thanks for the bug report. Can't believe I don't have a test case for that, despite the behaviour being mentioned in the README. The code looks like it's trying to do it:

titlecase/src/lib.rs

Lines 115 to 116 in 9366767

	} else if SMALL_RE.is_match(word) {
	word.to_lowercase()

But I suspect the \A and \z in SMALL_RE are not right.

titlecase/src/lib.rs

Line 81 in 9366767

static ref SMALL_RE: Regex = Regex::new(&format!(r"\A(?:{})\z", SMALL_WORDS.join("|")))

Having tried to do it by myself, I suspect you need lookbehind/lookahead constraints if you want to do it with regexp, which Rust don't have. So, a manual scanner may be needed.

Published v2.1.0 with a fix for this.
