[9fans] right arrow blocked before closing bracket

[9fans] right arrow blocked before closing bracket

[Mark van Atten]

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: [ ], ( ), < >.

In p9p acme, and also in Plan 9 sam and rio, this works fine.

Perhaps a patch already exists?

Mark.

That is very quick---thanks, Erik! I just tried out the patch on Bell
Labs Plan 9, and it works fine.
