I recently ran into a problem with this; I had a regexp with `-' at the
end, then edited it to add another range, without noticing the trailing
`-':

before: [0-9a-zA-Z_-]
after: [0-9a-zA-Z_-\x80-\U0010FFFF]

This is _not_ what I wanted.

So putting it first is better. It does not conflict with putting `]'
first;

[]-...]

is unambiguous.
