Would help by not having to type '#mine iron_ore gold_ore emerald_ore' or another long string of names, would also help with mods with many different ores. For example.

#mine ore = Mines anything that ends in 'ore'.
#mine ore = Mines anything that has 'ore' anywhere in it.
#mine ore = Mines anything that starts in 'ore'

I think that the idea suggested in #3047 is more versatile than this and would implement the same functionality, so I'm going to close this issue.
