Source code has mixed newline styles which makes it hard to create clean diff

I'm trying to prepare a pull request, but because of mixed newline styles in the original source code I cannot make a clean diff (i.e. each line is seen as difference). Can you please fix this?

To make it a file with proper Unix newlines you can do something like: cat pqselect.dev.js | tr '\r' '\n' > pqselect.dev.js.proper

Thanks!
