+The @code{\once} prefix may also be used in front of many

+However, predefined commands of the form @code{\@dots{}Neutral},
+@code{\@dots{}Off} and @code{\un@dots{}} use @code{\revert} internally
+rather than @code{\override} so prefixing these with @code{\once} has no
+effect.

The command to revert to the default behavior is
-@code{\textLengthOff}. Remember @code{\once} only works with
-@code{\override}, @code{\set}, @code{\revert} or @code{\unset},
-so cannot be used with @code{\textLengthOn}.
+@code{\textLengthOff}. Alternatively, @code{\once} may be used
+with @code{\textLengthOn} if the effect is to be limited to just a
+single musical moment.
+The corresponding spacing behavior for rehearsal marks and tempo
+indications is independently controlled with the commands
+@code{\markLengthOn} and @code{\markLengthOff}.

@noindent
By default, outside-staff objects are given a width of zero so
that they may overlap in the horizontal direction. This is done
-by the trick of adding infinity to the leftmost extent and
-minus infinity to the rightmost extent by setting the
-@code{extra-spacing-width} to @code{'(+inf.0 . -inf.0)}. So
-to ensure they do not overlap in the horizontal direction we
-must override this value of @code{extra-spacing-width} to
-@code{'(0 . 0)} so the true width shines through. This is
-the command to do this for dynamic text:
+by the trick of making the leftmost extent infinity and
+the rightmost extent minus infinity by setting the
+@code{extra-spacing-width} to @code{'(+inf.0 . -inf.0)}. To
+ensure they do not overlap in the horizontal direction we
+must override this value of @code{extra-spacing-width} to give them
+a little extra spacing. The units are the space between two staff
+lines, so moving the left edge half a unit to the left and the
+right edge half a unit to the right should do it:
@example
-\override DynamicText.extra-spacing-width = #'(0 . 0)
+\override DynamicText.extra-spacing-width = #'(-0.5 . 0.5)
@end example

-Well, it has certainly stopped the dynamic marks being
-displaced, but two problems remain. The marks should be
-spaced a little further apart and it would be better
-if they were all the same distance from the staff.
-We can solve the first problem easily. Instead of making
-the @code{extra-spacing-width} zero we could add a little
-more to it. The units are the space between two staff
-lines, so moving the left edge half a unit to the left and the
-right edge half a unit to the right should do it:
