" Forward slashes are changed to back slashes so path equality works better
" on Windows. Back slashes are changed to forward slashes on Unix.

" Unix paths can technically contain back slashes, but in practice no path
" should, and replacing back slashes with forward slashes makes linters work
" in environments like MSYS.

" Paths starting with more than one forward slash are changed to only one
" forward slash, to prevent the paths being treated as special MSYS paths.
