Bug Description

Create a document with a few layers (for example, the attached). Open the undo history and layers dialog.

Right click on a layer and show/hide other layers. Then do it again for the same layer. Note that the undo history doesn't record the second time.

Seen on Inkscape 0.91 x64 on Windows 8.1.

Match 'Importance' to similar earlier report concerning layer changes and undo history (bug #1256463).

Please comment if you disagree, or if this corrupts the undo history and can lead to crashes later on.

From src/document-undo.cpp:

" * \verbatim
   void sp_document_done( SPDocument *document );
   void sp_document_maybe_done( SPDocument *document, const unsigned char *key ) \endverbatim
 * Both move the recent action list into the undo stack and clear the
 * list afterwards. While the first method does an unconditional push,
 * the second one first checks the key of the most recent stack entry. If
 * the keys are identical, the current action list is appended to the
 * existing stack entry, instead of pushing it onto its own. This
 * behaviour can be used to collect multi-step actions (like winding the
 * Gtk spinbutton) from the UI into a single undoable step."

Thus calling DocumentUndo::done for SP_VERB_LAYER_SOLO and SP_VERB_LAYER_LOCK_OTHERS in verbs.cpp would add a different undo history entry each time the actions are performed instead of one (all actions can be undone with a single undo action) currently.
