Pre-2012, git-gui enabled the "Repository->Explore Working Copy" menu on Cygwin, offering open a Windows graphical file browser at the root working directory. The old code relied upon internal use of Windows pathnames, while git-gui must use unix pathnames on Cygwin since 2012, so was removed in a previous patch.

A base install of Cygwin provides the /bin/cygstart utility that runs arbtitrary Windows applications after translating unix pathnames to Windows. Adding the --explore option guarantees that the Windows file explorer is opened, regardless of the supplied pathname's file type and avoiding possibility of some other action being taken.

So, teach git-gui to use cygstart --explore on Cygwin, restoring the pre-2012 behavior of opening a Windows file explorer for browsing.
