Summary:                    tab characters in paths causes errors in initial
configure step
Description: 
I was testing a problem with building FFTW as an external project in ITK --
specifically that FFTW can't configure if the source or build directories have
whitespace characters in the directory path.

I created a build directory with space characters in it, and CMake had no
problem with configuration, and I verified my test for paths w/whitespace
characters worked properly.

I then created a build directory with tab characters in it.  This seemed to
break the initial CMake configure run, in the CMakeBackwardCompatibilityC
module.

Steps to Reproduce: 
#!/bin/sh
# This script will produce the behavior I observed
mkdir -p cmake_tabs_bug/cmake_tabs_bug
cd cmake_tabs_bug/cmake_tabs_bug
cat > CMakeLists.txt <<EOF
project(cmake_tabs_bug)
cmake_minimum_required(VERSION 2.8.2)
include(CMakeBackwardCompatibilityC)
include(CMakeBackwardCompatibilityCXX)
EOF
cd ..
# this path should be 'build\ttabs'
mkdir 'build	tabs'
cd 'build	tabs'
cmake ../cmake_tabs_bug
