This fixes a bug where using \A or (?-m)^ in combination with -U/--multiline would permit matches that aren't anchored to the beginning of the file. The underlying cause was an optimization that occurred when mmaps couldn't be used. Namely, ripgrep tries to still read the input incrementally if it knows the pattern can't match through a new line. But the detection logic was flawed, since it didn't account for line anchors. This commit fixes that. Fixes #1878, Fixes #1879
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"
and this to your crate root:
extern crate grep_regex;
