port mirror --new pseudoport behaves unexpectedly

[danielluke (Daniel J. Luke)]

port mirror --new pseudoport deletes the distfiles_mirror.db before processing each port in the expanded pseudoport, so the end result is simply a distfiles_mirror.db with only the last port from the expanded pseudoport.

If it only deleted the file once per run, it would be possible to do:

port mirror --new installed portmirror

to delete all of the distfiles that aren't the current ones for installed ports...

(as is, one can work around this by doing port mirror --new some_installed_port && port mirror installed && portmirror)
