Indeed the seekg is returning success so my code uses the path where it is
expected to work. If I force buffering, the test passes.
I tried the same tests in PowerShell instead of Git for Windows Bash. There too
seekg() reports success. If I force buffering tellg() after isp->seekg(0,
ios_base::end) reports 171,926 bytes vs a file size of 170,512 which is
strange. Without buffering tellg() reports 8192 bytes. Basically the same
behaviour as with G4W bash except there tellg() reports 170,512 bytes and
126,976 bytes respectively.

If Cygwin consumers also see this changed seekg behaviour then they will have
problems too.
