+Patch 7.2.266
+Problem: When an expression abbreviation is triggered, the typed character
+ is unknown.
+Solution: Make the typed character available in v:char.
+Files: runtime/doc/map.txt, src/eval.c, src/getchar.c, src/ops.c,
+ src/proto/eval.pro

+ The result of the InsertDot() function will be inserted. It could check the
+ text before the cursor and start omni completion when some condition is met.
+
++ For abbreviations |v:char| is set to the character that was typed to trigger
++ the abbreviation. You can use this to decide how to expand the {lhs}. You
++ can't change v:char and you should not insert it.
++
+ Be very careful about side effects! The expression is evaluated while
+ obtaining characters, you may very well make the command dysfunctional.
+ For this reason the following is blocked:
