It works in a limited manner.  For instance, if the line is the last line
of the file, the J will fail, and the command will abort.  If the entire
line is contiguous nonwhite characters the B will place the cursor in the
first column, wherupon the ^H will fail, aborting the command.

I like it, though, primarily because it uses the | in a map, which I
used to think was impossible.
