grep-use-null-device is a variable defined in ‘grep.el’.
Its value is ‘auto-detect’
Documentation:
If t, append the value of ‘null-device’ to ‘grep’ commands.
This is done to ensure that the output of grep includes the filename of
any match in the case where only a single file is searched, and is not
necessary if the grep program used supports the ‘-H’ option.
In interactive usage, the actual value of this variable is set up
by ‘grep-compute-defaults’; to change the default value, use
Customize or call the function ‘grep-apply-setting’.
You can customize this variable.
