mkdir, would be great to have
For example, if I have a folder
Trash/2010 that I would like to delete, I envision something like...
A safety feature might be that if the folder is not empty, that it prompts for confirmation.
Alternately (and probably safest), it could refuse to delete a folder that is not empty, instead you have to either clear it out first or
:rmdir -f Trash/2010
