Problem Compiling Docs using make.py 
When there is a space in the name of a parent directory, make.py fails to run. 

```
$ python make.py html
```

This is the output of the command: 
```
usage: sphinx-build [OPTIONS] SOURCEDIR OUTPUTDIR [FILENAMES...]
sphinx-build: error: cannot find source directory (/Users/usr/Documents/Pandas Sprint/pandas/doc/Sprint/pandas/doc/build/doctrees)
```

However, when after removing the space from the directory name (i.e. change 'Pandas Sprint' to 'PandasSprint') the python script executed as expected. 

Hope this helps.
