[Message part 1 (text/plain, inline)]

I agree it's an ill defined problem ; but then, so is isearching for
foo\|bar.

I disabled the beeping and screen flashing, so it doesn't bother me, but I
get the point.

In the end, it's mostly a matter of personal convenience. The patched
behavior suits me better, and seems more consistent with the way regexp are
handled.

Best,
Antoine

I think this is a consequence of the simple fact that "word search"
and "incremental search" contradict each other: as long as "the word"
was not fully specified, searching for it incrementally is not a
well-defined operation.
