[TxMt] replace text bug in 1.5.7?

[DushanM]

I've just updated TextMate a couple of days ago to 1.5.7 from 1.5.6, and
am noticing what seems to be a bug when replacing text.  Here's what
happens.  If I'm in a Plain Text document, and specify to replace the
string X with the string Y, the first instance of X is first prepended
with Y, then all the Xs are replaced with Y.

This didn't happen with the previous versions of TextMate that I used,
starting with 1.5.4, I think.  I'm using TextMate under X.4.10.  Anyone
else seen this?
