[PATCH] gitk: Avoid issues with script path format

[PATCH] gitk: Avoid issues with script path format

[Steven Penny]

Tk’s "wish" for Windows can be built two ways

win   this provides a "wish" that uses GDI; it only understands Windows
      paths such as C:\foo\bar
unix  this provides a "wish" that uses X11; it understands Windows and Cygwin
      paths such as C:\foo\bar or /foo/bar

Some Cygwin users will prefer to use the "win" version, as it avoids the large
X11 dependency. However Cygwin passes the path "/bin/gitk" or similar and the
"win" version of "wish" will not understand this. However "wish" does understand
STDIN. Options such as "--all" will still work using this method as well.
