*Problem:* edit_command_buffer uses `cat` to return the modified content. If a person has an alias for `cat` to a different command such `bat`** the editing will not be useful anymore since bat decorates the text with frames, line counts, etc *Solution* Appending command to cat, fish will ignore the alias and execute the real command according to this https://fishshell.com/docs/current/cmds/command.html ** https://github.com/sharkdp/bat
