It's in the ChangeLog, dated 12-Feb-99.

I have a patch, made for me at home. It's not very clean, I fear, but
if you think that it's ok...
It handles the two cases, to rename a file with only changing the
case (first additional line) or changing `foo.exe' to 'foo', including
changing the case (next three lines).
I have patched earlier `ln' and `cp', to eliminate the boring `.exe'
problem with the three line patch. I have attached this patches, too.

Regards,
Corinna
