I am personally not thrilled by what this series attempts to do, but first a few questions:

 - Are there existing non-git "grep" implementations that do this?
 - If yes:
   - what command option letter do they use to specify line number?
   - do they not support a range notation (e.g. -@ 25-30,32-40)?
   - what do they do when given more than one file?
 - If no:
   - why not?  Is it a sign that this is ill-thought out misfeature?
   - perhaps people use something like "sed -n -e 25,30p file" and be
     happy?
