The latter reads more naturally, but the former is more specific
and might avert future threads like this one.  Then again, the man
page already uses both -- seemingly interchangeably -- so either
would probably be sufficient.

The original quote is actually fine then, but other sentences could
be improved.  For example:

        A sequence expression takes the form {x..y[..incr]}, where
        x and y are either integers or single characters [...]
