		In Plan 9 acme, if you type

		{}

		then go back and type text between the brackets

		{Curiouser and curiouser!}

		the right arrow is blocked when you want to go over the closing
		bracket to continue typing to its right. (If you first go to the left,
		and then back to the right, it works.)

		Same for the other brackets: [ ], ( ), < >.

	noted that brackets are not necessary.  same behavior with any
	character.

	fix is to textcommit before moving.
