While gitk is most likely installed as /usr/bin/gitk in Cygwin's 
filespace, that could resolve to anything in the Windows file system. It 
might be c:\cygwin\usr\bin\gitk, but could also be "d:\Documents and 
Settings\Bill\Programs\cygwin\usr\bin\gitk" depending upon who installed 
it and with what options. Both are seen as /usr/bin/gitk by Cygwin. 
Thus, Shawn is correct in using cygpath to resolve the name.

Also, as Cygwin's tcl/tk package is bound to the port of the insight 
debugger to Cygwin, and that project is stuck for years on 8.4.1, this 
patch (or something like it) may be the only way to allow gitk to access 
a more recent version on Cygwin in the foreseeable future. So, I think 
this is a good idea.
