Using either ag or rg on dos line-encoded files shows ^M characters at the buffer

[r-darwish]

When using either counsel-ag or counsel-rg to search something in a DOS line-encoded project, ^M characters appear in the buffer. When I press C-c C-o these characters also appear in the ivy-occur buffer. wgrep does not work as a result. Emacs grep command does not display the ^M characters.

See counsel-async-split-string-re.

Customization of the variable like below works for both unix and dos line endings for me:

(setq counsel-async-split-string-re "\r?\n")

Thanks.
