there's a syntax error.  (In particular, display the correct
filename).  This changes the API: if there's a syntax error, the
function now returns normally after dumping the error to sys.stderr.
I changed Sjoerd's use of string.join(string.split(...)) with
string.replace().

works and Greg Ward just reported a problem it caused...

1. Generate a correct Content-Length header visible through the info() method
   if a request to open an FTP URL gets a length in the response to RETR.

2. Take a third argument to urlretrieve() that makes it possible to progress-
   meter an urlretrieve call (this is what I needed the above change for).
   See the second patch band below for details.

3. To avoid spurious errors, I commented out the gopher test.  The target
   document no longer exists.

not really a good solution for default input strings...

the de-queing of exec files work for NT XEmacs 21.0.

before code has been checked for validity.  Discovered by Vladimir
Marangozov.

when in an interactive session (suggested by B. Wiener).

string in the argument to execfile() so a Windows temp directory
named, e.g. c:\\tmp doesn't get interpreted as a file name with an
embedded tab!  (given by C. Waldman).

InteractiveInterpreter, which handles parsing and interpreter state
but doesn't know deal with buffering or prompting or input file
naming.  And a derived class, InteractiveConsole, which adds buffering
and prompting and supports setting the filename once.  Also tweak the
algorithm in compile_command() a bit so that input consisting of all
blank lines or comments always succeeds immediately, and note the fact
that apart from SyntaxError it can also raise OverflowError.

this string should not end with whitespace.

(py-compute-indentation): Append whitespace regexp to
py-block-comment-prefix so that any combination of intervening
whitespace will be recognized.
