 By default, this will send the whole subvolume. To do an incremental
 send, use '\fI-p <parent>\fR'. If you want to allow btrfs to clone from
 any additional local snapshots, use '\fI-c <clone-src>\fR' (multiple times
 where applicable). You must not specify clone sources unless you
 guarantee that these snapshots are exactly in the same state on both
-sides, the sender and the receiver. It is allowed to omit the
-'\fI-p <parent>\fR' option when '\fI-c <clone-src>\fR' options are given, in
+sides, the sender and the receiver. It is allowed to omit the '\fI-p <parent>\fR'
+option when '\fI-c <clone-src>\fR' options are given, in
 which case '\fBbtrfs send\fP' will determine a suitable parent among the
 clone sources itself.
