+Patch 7.3.591
+Problem:    Can only move to a tab by absolute number.
+Solution:   Move a number of tabs to the left or the right. (Lech Lorens)

+  REORDERING TAB PAGES:
+  
+  :tabm[ove] [N]						*:tabm* *:tabmove*
++ :[N]tabm[ove]
+  		Move the current tab page to after tab page N.  Use zero to
+  		make the current tab page the first one.  Without N the tab
+  		page is made the last one.
+  
++ :tabm[ove] +[N]
++ :tabm[ove] -[N]
++ 		Move the current tab page N places to the right (with +) or to
++ 		the left (with -).
++ 
++ Note that although it is possible to move a tab behind the N-th one by using
++ :Ntabmove, it is impossible to move it by N places by using :+Ntabmove. For
++ clarification what +N means in this context see |[range]|.
