[GRASSLIST:7742] v.digit oops - backup command

[M S]

Ok... so i 'm happily v.digitizing away... and i delete something i
didnt want to, or do some operation i made a mistake on (moved vertex,
etc..).

is there a way to "back up"? in other software it keeps an audit trail
of transactions and you can "oops" back through all the transactions,
in effect restoring vector digizing operations performed....

is there something similar in GRASS v.digit?

thanks!
