For what it's worth, I always want to search for sequences but find
it more convenient to enter the numbers space-separated, so I've long
used a local helper function to put the commas in for me.

I'm sure there's a genuine use-case to search for non-consecutive
sequence entries, and that there should be specific support for this.
Quoting all of the values doesn't feel ideal for that though, better
would be some one-off prefix.
