Backward search performance is terrible using :-/xxx

[tiancaiamao]

In acme, you can use right click on:+/xxx to search string xxx, it search from the forward direction. There is also a :-/xxx to seach from the backward direction.

In acme, the backword search is basically the same with the forward search. However, in edwood, :-/xxx is very slow, an order of magnitude slower than :+/xxx

That's the golang regexp library vs the hand-coded one in acme. This is probably a strong enough argument to do regexp in edwood directly, though that's at high engineering cost.

First duplicate bug! That's sort of exciting. We should fix this. Tracked in #301
