I'm fully aware of it, of course. Given the binary search, it should around
the loop about 5-7 times, and substitute-in-file-name shouldn't do that much
consing itself, so I figured it was worth trying.
Also we could easily optimize the common case (where the overlay is not
moved) using a total of 3 calls to substitute-in-file-name in the
common case.
But given the fact that icomplete.el has been usable for a long time
already, I suspect that the performance issue is only in our heads,
Stefan
