Description

Regular expressions containing newlines (\n) do not find any matches when doing a project-wide search.

Steps to Reproduce

1. Create a file in a project containing at least one newline (with unix line endings to avoid CR/LF confusion).
2. Start up project-wide search, in regex mode.
3. Type in \n and confirm that the newlines in the file are highlighted (as the automatic current-file search runs).
4. Press enter to perform the search across the entire project.

Expected behavior: All instances of the regex should be found.

Actual behavior: No instances of the regex are found.

Reproduces how often: Every time.

Versions

Atom 1.25-beta0, Windows 10, x64 - although this is not the first version it occurred in. I'm not sure when/if this was ever working.

This is a consequence of #218 - project-wide searches currently search line-by-line. Feel free to subscribe to that issue for updates.
