relate issue: #317

The buffer mode is a variant from unrestricted mode, for example:

The launching command is:

• for rg: rg --column -n --no-heading --color=always -S -uu '' lua/fzfx/config.lua
• for grep: grep --color=always -n -H -r '' lua/fzfx/config.lua

Also removed the -- flag in rg/grep launch command for other modes.
