unzip in git bash

"Git for Windows" vs "msysGit",
msysGit includes unzip, while Git for Windows does not.

""" ...

Think of Msysgit as Windows programs that emulate Linux behavior.
Msysgit executables are regular Windows executables, just like 7-zip.exe

...


the files in C:\msysgit\share\7-Zip are the regular
Windows versions, not a special Mingw-compiled version of 7-Zip
