It turns out that if there are text anchors (that is, \A or \z, or ^/$ when multi-line is disabled), then the "fast" line searching path isn't quite correct. Since searching without multi-line mode is exceptionally rare, we just look for the presence of text anchors and specifically disable the line terminator option in 'grep-regex'. This in turn inhibits the "fast" line searching path. Fixes #2260
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.

Documentation
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"
