RE: Default value of next-error-highlight is too small

[Drew Adams]

    This should implement highlighting until next input event.
    Does it work?

Bravo! Beautiful. I think this should be the default behavior: leave the
highlighting on (no timer) until the next input event.

Personally, I might still use `t', to leave it on until the next use of
`next-error'. That way, it won't disappear when I select the *grep* buffer.
But your change should be what we use as the default behavior, IMO.

Thx!
