[racket] XREPL ,en in 5.3 doesn't re-evaluate?

To follow up and narrow this:

This is limited to XREPL's ,en.  If you `touch' a file, then ,en will
_not_ re-evaluate it in 5.3 (but it _would_ in 5.2.1 and earlier).

By contrast, enter! in 5.3 behaves the same as in 5.2.1.  If you
`touch' a file, enter! _will_ re-evaluate it in both versions.

This is on OS X 10.7.4 in case that would matter (?).


I tweaked my emacs config to use enter! instead of XREPL's ,en. So I
have no practical problem anymore. However I wanted to point this out
in case the change in behavior mattered to someone else.
