    Only the base part of startPath is kept, since this routine is typically
    used with a script's ``__file__`` variable as startPath. The base of startPath
    is then prepended to all the listed files, forming the output list.

    Parameters
    ----------
    startPath : string
      Initial path to use as the base for the results.  This path is split
      using os.path.split() and only its first component is kept.

    files : string or list
      One or more files.

    Examples
    --------

    >>> full_path('/foo/bar.py',['a.txt','b.txt'])
    ['/foo/a.txt', '/foo/b.txt']

    >>> full_path('/foo',['a.txt','b.txt'])
    ['/a.txt', '/b.txt']

    If a single file is given, the output is still a list::

        >>> full_path('/foo','a.txt')
        ['/a.txt']

    Return appropriate IPython command line name. By default, this will return
    a list that can be used with subprocess.Popen, for example, but passing
    `as_string=True` allows for returning the IPython command as a string.
