guess the mime type of a local file.

Change suggested by Sjoerd (with different implementation):
  when retrieve() creates a temporary file, preserve the suffix.

Corrollary of the first change:
  also return the mime type of a local file in retrieve().

Logical markup.

One more index entry.

Be more specific about an exception raised by range().

Minor nits.

Describe UserDict and UserList individually so they aren't too hideous in
the presentation.

Consistency nits.

ACKS file should be checked....).

Add a manpage reference.

Add an index entry.

Add {excdesc} for zlib.error.

Use {methoddesc} where appropriate.

in the same module.

Lots of index entries.

Use math-mode pi instead of mixing forms.

Use spaces around relational operators.

Moved IGNORECASE & friends to "top level" definitions following compile(),
since there is no other case of nesting in the manual.

Use {memberdesc} and {methoddesc} as appropriate.

Indent code sample to use 4-space indents.

Index entry.

Moved stuff from "Recent Additions to 1.1" to "More on Defining Functions".
This means there's now a short section on "Defining Functions" immediately
followed by a long section "More on Defining Functions."

Add an index entry.

Document ArrayType.

Use {memberdesc} and {methoddesc} environments, as appropriate.

Minor nits.

Added comments to various sections.

Big fix:  the module index for the Python Library Reference is once more in a
separate file!  Yeah!

(Still no __setitem__, until I get a request to add it!)

special markup for the first column of a table using {tableii} or {tableiii}.
In LaTeX, this requires using "textrm" as the formatting function, and this
is needed to remove the bogus "<textrm>" that gets generated otherwise.
There should probably be a more general mapping of specified markup to useful
markup, but that doesn't appear needed at the moment.

do_env_tableii(), do_env_tableiii():  If the markup for the first column is
	\textrm, make it empty.

do_cmd_lineii(), do_cmd_lineiii():  If the markup for the first column is
	empty, don't add markup around the text.
