/mis-wort/ [By analogy with misbug
] A feature
that superficially appears to be a wart
but has been determined to be the Right Thing
For example, in some versions of the Emacs
text editor, the "transpose characters" command exchanges the character under the cursor with the one before it on the screen, *except* when the cursor is at the end of a line, in which case the two characters before the cursor are exchanged.
While this behaviour is perhaps surprising, and certainly inconsistent, it has been found through extensive experimentation to be what most users want.
This feature is a miswart.
