Ah, so I've misunderstood what you meant.  I thought you were talking
about including Git in PATH.

Yes, the bin directory where all the binaries are installed should be
on PATH.  The MinGW and MSYS installation instructions in nt/INSTALL
already have that described in detail, including a couple of caveats.

But I see now that I was mistaken even in my interpretation: a recent
change to autogen.sh invokes Git from that script, to install Git
hooks.  So I changed nt/INSTALL to include that bit.
