Numeric brace expansion containing parameter
We now support expansion like this:
$ set -o braceexpand $ d=. o=1 $ echo {1${d}${d}3} {${o}..3} 1 2 3 1 2 3
This may possibly be a cause of unexpected expansion, for example, like echo {${var}} where var='1..3'.
On the other hand, it would still be useful if the range of numeric brace expansion could be specified by parameters: echo {${from}..${to}}
So my current opinion is that the braces and dots must be literal (not from parameter expansion) but the numbers can be a parameter.
(This behavior is different from that of other shells, though...)
