gitk: handle external diff tool with spaces in the path
PATCH 1/1 gitk: handle external diff tool with spaces in the path
This fixes the launching of external diff to handle a diff tool that has spaces in the path. This patch ensures a correctly formed tcl list is passed to the open command with a single pipe character prefixing the list (as per the tcl manual page for open).
The specific fault observed was that selecting WinMerge as the diff tool from the default installed location in Program Files failed to be launched from the context menu.
