   Yeah, and just that one. The other is, of course, not affected because   
   it doesn't invoke grep.

   Would it be preferrable to just subtract one?   
      
   I think another approach is to add [ and ] around one letter of what   
   you're filtering for, but that'd require modifying the string, and   
   shares one issue with "grep -v grep": it doesn't work as intended if the   
   name you are grepping for is grep.   
      
   (But then we also have to consider words being something other than   
   argv[0]. 'ps axo comm', perhaps?; Is that 'ps -eo comm' in POSIX   
   syntax?)
