patch: do not break up multibyte character when highlighting word

This changes {\W} to {\W - any 8bit characters} so that multibyte sequences
are taken as words. Since we don't know the encoding of user content, this
is the most sensible definition of a non-word.

fixbundle() {
    grep -v 'saving bundle' | grep -v 'saved backup' | \
        grep -v added | grep -v adding | \
        grep -v "unable to find 'e' for patching" | \
        grep -v "e: No such file or directory" | \
    cat
