E64 in :help completion.

[mattn]

Hi.

Try to type following into command line.

:help \{-

And type <tab>. You'll see error message, and you'll see broken command line.

:help E64

The words should be kept on the command line after displaying E64.
Below is a patch.

Thanks. However, I think it's better to check if regprog is NULL.

And we also need to avoid the error.
