bad double quote parsing (appears to be all commands)

[jhudsoncedaron]

Behold:

D:\>"c:\Program Files\coreutils\bin\printf.exe" %s-%s-%s "a""a" "a""a" "a""a"
a"a aa aa--

If I run this through cygwin the expected output appears:

D:\>"c:\cygwin64\bin\printf.exe" %s-%s-%s "a""a" "a""a" "a""a"
a"a-a"a-a"a

So far I've tried this with printf, echo, and xargs but I think all commands are affected.

What I'm trying to do: find | xargs sed -i where the replacement string contains double quote characters.
