Parsing fails for multiline comments and markdown with windows linebreaks

[DrChainsaw]

Thanks for this awesome package. Very powerful and easy to use!

Seems like the regex does not catch windows line breaks. As a piece of clear evidence that computers are consipiring against us, the method used in testing serves as a workaround :/

julia> mdstr = """
           md\"\"\"
           bla
           \"\"\"
           """

julia> mktempdir() do path
       testfile = joinpath(path,"testfile.md")
       write(testfile, mdstr)
       match(r"^md\"\"\"$\R^(\X*?)\R^\"\"\"$"m, read(testfile, String))
       end
RegexMatch("md\"\"\"\nbla\n\"\"\"", 1="bla")

# This file is created using "new file" in VS code
julia> read("mdtest.jl", String)
"md\"\"\"\r\nbla\r\n\"\"\""

julia> match(r"^md\"\"\"$\R^(\X*?)\R^\"\"\"$"m, read("mdtest.jl", String))

The regex works when tested in Rubular. Replacing \R with (?:\r?\n) does nothing, but removing the begin/end of line markers makes it work.

This seems to be a way to create windows linebreaks inside Julia:

julia> mdstr = "md\"\"\"\r\nbla\r\n\"\"\""
"md\"\"\"\r\nbla\r\n\"\"\""

julia> mdstr == read("mdtest.jl", String)
true

julia> mktempdir() do path
       testfile = joinpath(path,"testfile.md")
       write(testfile, mdstr)
       match(r"^md\"\"\"$\R^(\X*?)\R^\"\"\"$"m, read(testfile, String))
       end

Thanks, I thought it was happening after (

Literate.jl/src/Literate.jl

Line 151 in 65f55d3

push!(repls, "\r\n" => "\n") # normalize line endings

) but that is just pushing replacements to a vector and doing the replacement later
