What would be the "right thing to do"? Should we call grep and ugrep with
"--binary-files=text" (and ripgrep has the equivalent "-a") and then ask
Emacs to guess whether each match is "compatible" with the process encoding
system and based on that decide whether to display the match or print a
warning like "match found among unprintable binary data" nearby the file
name?
