Notably the @code{\tweak} command cannot be used to modify stems,
-beams or accidentals, since these are generated later by note heads,
-rather than by music elements in the input stream. Nor can a
-@code{\tweak} command be used to modify clefs or time signatures,
-since these become separated from any preceding @code{\tweak}
-command in the input stream by the automatic insertion of extra
-elements required to specify the context.

But the @code{\tweak} command can be used as an alternative to
the @code{\override} command to modify those notational elements
curve's control points.
For the example above the following override gives a satisfactory
-tie:
+tie. Note the placement -- it has to be immediately before the note
+to which the start of the tie (or slur) is attached.
