Ah, that's good, I'll use that - thank you. Introduced in bash 3.2.2 I see.

No, I'm using "native" Cygwin git 1.7.1 on Cygwin 1.7.5.

A quick test (with core.autocrlf=3Dtrue) clearly shows all cloned files
as being in CRLF format. Would you like me to test with the latest
Cygwin?

Indeed. We've been using Cygwin git for two+ years now, and the
line-endings issue is a major and constant headache, but I've posted
all that months ago (and without resolution). These days we just
delete and reclone when the dreaded
line-endings-prevent-checkout-or-commit-or-anything problem raises its
head :)
