Hi,

I recently faced some error messages when using git submodules. I found, that Cygwin's git works nicely on its own. But when I have MSYS binary paths in my environment, Cygwin's git finds the msys gettext and envsubst binary and tries to use it, resulting in error messages (see below). I did solve the issue, by installing Cygwin's gettext (which git does not seem to be requiring).
I write, because I found it somewhat odd, that Cygwin's git is not dependent on gettext, but uses it, if it finds it somewhere in the path environment. Just to emphasize, in my Cygwin environment all Cygwin paths come first. So it was only using the wrong msys binary, because there was none in Cygwin.
Is this behaviour expected and intended or could it be mitigated during installation somehow?

Just for completeness: I am using Cygwin and msys updated to the latest versions.
The original error message:

$ git submodule update

Cheers,
Andreas
