As the error suggests, the --from-patch option takes a regular
expression: "*recursive*" is not a valid regex, and thus darcs
complains.
You can either provide a valid one, such as ".*recursive.*", or more
simply forget about the stars, as "recursive" is a valid regex on its
own and darcs will do what you meant above :-)
hope this helps,
ciao, lele.
