When using the folder search, find the results. My search is a regular statement, open a single file the same use of this regular statement is no problem.
My regular "^\s*$\n", the purpose is to remove the blank line

^\s*$\n won't work because multiline search isn't supported. But I just fixed it so ^\s*$ will work, without the newline.

@roblourens Above regex is showing invalid results. Also the results view looks broken

[roblourens]

rg is returning some extra incorrect results. The results view is correct though since it's supposed to be matching empty lines.

Fixed upstream, need 0.7.0+ BurntSushi/ripgrep#599
