regex: fix -w when regex can match empty string 
This is a weird bug where our optimization for handling -w more quickly
than we would otherwise failed. In particular, if the original regex can
match the empty string, then our word boundary detection would produce
invalid indices to the start the next search at. We "fix" it by simply
bailing when the indices are known to be incorrect.

This wasn't a problem in a previous release since ripgrep 13 tweaked how
word boundaries are detected in commit efd9cfb2.

Fixes #1891

grep-regex

The grep-regex crate provides an implementation of the Matcher trait from the grep-matcher crate. This implementation permits Rust's regex engine to be used in the grep crate for fast line oriented searching.

Build status

Dual-licensed under MIT or the UNLICENSE.

Documentation

https://docs.rs/grep-regex

NOTE: You probably don't want to use this crate directly. Instead, you should prefer the facade defined in the grep crate.

Usage

Add this to your Cargo.toml:

[dependencies]
grep-regex = "0.1"
