This patch adds a helper function with similar semantics to
vshCommandOptString that requests a string argument, but does some
error
reporting without the need to do it in the functions themselves.
The error reporting also provides information about the parameter
whose
retrieval failed.

Not in virsh.c. All surrounding functions don't have the colon in the
comment. This is worth cleaning up separately instead of doing it in
multiple ways in a single file.
Agreed, a follow up patch will be good then. But others still stands.
I changed the comment to:
/**
+ * vshCommandOptStringReq:
+ * @ctl virsh control structure
+ * @cmd command structure
+ * @name option name
+ * @value result (updated to NULL or the option argument)
+ *
+ * Gets a option argument as string. This function reports errors.
I think "The function reports errors" can just be removed. As it
doesn't report any error on success.
Okay.

ACK with that.
