@code{skeleton-transformation} when that is non-@code{nil}.
@item @code{?\n}
@c ??? something seems very wrong here.
-If not at end of line, insert a newline and align under current line.
-Use newline character @code{?\n} to prevent alignment. Use
-@code{"\n"} as a string to insert a newline unconditionally.
+Insert a newline and align under current line, but not if this is the
+last element of a skeleton and the newline would be inserted at end of
+line. Use newline character @code{?\n} to prevent alignment. Use
+@code{"\n"} as the last string element of a skeleton to insert a
+newline after the skeleton unconditionally.
@item @code{_}
Interesting point. When wrapping skeletons around successive regions, they are
put at these places. Point is left at first @code{_} where nothing is wrapped.
