Feature request: Print aliases with their flags

[morganestes]

I'd like to see aliases printed along with their companion flags when I use .print() or .usage(), either in parenthesis or part of the comma-separated string of long and short flags. Something like:

Usage: command [options]
    --start (--to)       The most recent changeset (commit) number.
    --stop (--from)      The oldest changeset (commit) number.
    --limit (--max)      The maximum number of changesets to retrieve. (default: 400)

or:

Usage: command [options]
    --start, --to, -t         The most recent changeset (commit) number.
    --stop, --from, -f        The oldest changeset (commit) number.
    --limit, --max, -x        The maximum number of changesets to retrieve. (default: 400)
