This is a mess, starting with the fact that you didn't quote "$ua"
and "$ub".

I don't see what advantage you think you're gaining by splitting the
message into pieces like that.  If I were you, I'd throw this whole
thing away and use a here-document:

cat <<'EOF'
Usage: grep -ir --exclude=\*.el --include=\*.{orig,texi}  \
   -C 8 "hilbert" /marshall/
EOF

Just place the entire message directly into the script, exactly as you
want it to be printed.  (There's a tab-indented variant, if you want to
go down that road, but start with the simpler version first.)
