Maybe I'm misunderstanding what you're saying, but '-Z' (uppercase) appears to 
be the flag for "Force grep to behave as zgrep." The '-z' (lowercase) is 
currently unused/invalid in our grep.

FWIW, I agree that the '--null' long option naming is annoying and gross. There 
does appear to be somewhat of a precedent for use of '-0' with grep-like tools. 
The ripgrep tool forgoes '-z/-Z' and instead opts for '-0' and the '--null' 
long option.
