Either user option or prefix argument, IMO.  And this should be
documented with the caveat that a VCS can decide that a file is binary
even when it is not.  For example, I've seen Git treating very large
parser.c files in tree-sitter grammar repositories as binary files for
some reason.  Another example is CVS on MS-Windows: best practice is
to checkout all the files with the -kb switch, so that the client
doesn't attempt to convert EOLs to the Windows CR-LF format (which
ruins some files).
