git-gui: treat file names beginning with "|" as relative paths
The Tcl 'open' function has a very wide interface. It can open files as
well as pipes to external processes. The difference is made only by the
first character of the file name: if it is "|", a process is spawned.
We have a number of calls of Tcl 'open' that take a file name from the
environment in which Git GUI is running. Be prepared that insane values
are injected. In particular, when we intend to open a file, do not take
a file name that happens to begin with "|" as a request to run a process.
