[PATCH 0/2] gitk: Fix error display when Tcl is too old

The following patch series cleans up error message reporting when your
version of Tcl is too old.

The old code checked the Tcl version first and then tried to report
the error with show_error.  show_error uses msgcat for translation but
msgcat is not yet initialized when we are checking the Tcl version
requirement.

The first patch moves the initialization of msgcat before the check
for the Tcl version.  This version will fail is msgcat is not
available.

The second patch handles the case where the msgcat package is not
available by providing a default mc procedure than just returns the
argument text unchanged (essentially bypassing message text
translation).

This lets us continue to use show_error as-is.

  gitk: Initialize msgcat before first use
  gitk: Provide a default mc function if msgcat is not available
