Which it is not, even in ASCII text files, unless you don't mind such
bugs as CR and LF matching punctuation characters. A better solution
for the ASCII character set would be to use a translate table.
Certainly you can use XLAT or more efficient equivalents.
However, I _did_ say, "if that is acceptable for non-alpha ..."
I'm not sure it is not for a minimalist rescuedisk grep.
By masking, lowercase will get stripped to uppercase, punctuation
and digits to things like DLE and <space> to NUL. This might
produce some false matches, but will _not_ skip true matches.
I don't mind this for my uses of grep. Actually, I'd like an option
of stripping the high bit without having to run it through `tr`.
