bug#36612: Expand "no" options

[Steven Penny]

Grep does not have a way to disable "-i", "-n" or "-r" options. Those options
could look like this:

   -N, --no-line-number
   -O, --no-ignore-case
   -S, --no-recursive

The single letter choices are not ideal, but "-I" and "-R" were already taken.
If these options existed, you could write a function like this:

   grep_bravo() {
      grep -i -n -r "$@"
   }

then if you passed the new arguments like this:

   grep_bravo -N -O -S charlie delta.txt

your arguments would override the function arguments, as they come after.
