If the environ vars TEMP or TMP contain spaces on w32 the on-line help
will not work. e.g. help('or') gives the message
 The system cannot find the file specified.
This is because pydoc.tempfilepager sets filename=tempfile.mktemp()
which will have spaces in it if TEMP does. The filename is then used to
constuct the system command:
 os.system(cmd + ' ' + filename)
which in windows ends up as os.system('more < FILE WITH SPACES'). The
filename should be quoted, e.g.
 os.system('%s "%s"' % (cmd,filename))
I only ran across this problem because I use uwin on windows and it sets
TEMP to a w32 style long path. The normal windows command shell uses
the dos spaceless sort form for the TMP and TEMP env vars so the problem
doesn't arise when python is invoked from there.
And isn't tempfile.mktemp() deprecated?
