I was trying to use the `Regex` feature where `^` and `$` match the start and end of individual lines instead of the whole string, and I noticed that:

```julia
$ match(r"does$"m, "this does\r\nnot work")

$ match(r"does$"m, "this does\nwork")
RegexMatch("does")

```

Is this as expected, or is this a bug?

This behavior depends on how the underlying regexp library was compiled. You can do this to override the default behavior:

```julia
julia> match(r"(*ANYCRLF)does$"m, "this does\r\nso work")
RegexMatch("does")

```

(See [the Wikipedia article on PCRE](https://en.wikipedia.org/wiki/Perl_Compatible_Regular_Expressions) for details, especially alternative versions of the EOL spec.)

Great explanation, thank you!
