+nil. This argument may contain any fancy split, that will be added as
+the last split in a `|' split produced by gnus-group-split-fancy,
+unless overridden by any group marked as a catch-all group. Typical
+uses are as simple as the name of a default mail group, but more
+elaborate fancy splits may also be useful to split mail that doesn't
+match any of the group-specified splitting rules. See

otherwise, a | split, that does not allow crossposting, will be
returned.
-if CATCH-ALL is not nil, and there is no selected group whose
-SPLIT-REGEXP matches the empty string, nor is there a selected group
-whose SPLIT-SPEC is 'catch-all, this group name will be appended to
-the returned SPLIT list, as the last element in a '| SPLIT.
-
For each selected group, a SPLIT is composed like this: if SPLIT-SPEC
is specified, this split is returned as-is (unless it is nil: in this
case, the group is ignored). Otherwise, if TO-ADDRESS, TO-LIST and/or
matches this regexp too, and if SPLIT-EXCLUDE is specified, RESTRICT
clauses will be generated.
+If CATCH-ALL is nil, no catch-all handling is performed, regardless of
+catch-all marks in group parameters. Otherwise, if there is no
+selected group whose SPLIT-REGEXP matches the empty string, nor is
+there a selected group whose SPLIT-SPEC is 'catch-all, this fancy
+split (say, a group name) will be appended to the returned SPLIT list,
+as the last element of a '| SPLIT.
