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-matcher

This crate provides a low level interface for describing regular expression matchers. The grep crate uses this interface in order to make the regex engine it uses pluggable.

Build status

Dual-licensed under MIT or the UNLICENSE.

Documentation

https://docs.rs/grep-matcher

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-matcher = "0.1"
