Well, the code isn't really supposed to need much maintenance. And it
becomes obsolete as soon as we switch to bash-4. I've already added
additional:
if [[ ${BASH_VERSINFO[0]} -ge 4 ]]; then
echo -n "${w^}"
else
# current snippet
fi
Anyway, given the comments and specific case, I doubt it should be
a real issue.

I consider that a pointless conversion, esp. that it doesn't
make a difference code-wise.
