subset of Win32 ShellExecute's functionality. Guido wants this because
IDLE's Help -> Docs function currently crashes his machine because of a
conflict between his version of Norton AntiVirus (6.10.20) and MS's
_popen. Docs for startfile are being mailed to Fred (or just read the
docstring -- it tells the whole story).
Changed webbrowser.py to use os.startfile instead of os.popen on Windows.
Changed IDLE's EditorWindow.py to pass an absolute path for the docs
(hardcoding ShellExecute's "directory" arg to "." as used to be done let
IDLE work, but made the startfile command exceedingly obscure for other
uses -- the MS docs are terrible, of course, & still not sure I
understand it).
Note that Windows Python must link with shell32.lib now! That's where
ShellExecute lives.
<file>.readlines() does not call <file>.readline() internally anymore,
and the sizehint parameter should be mentioned briefly.
Some displays of floating point numbers needed to be updated due to the
change in the repr() of floats (from 1.6).
Both issues were noted by Aahz <aahz@panix.com>.
'convert_paths()' method to convert them all to the local syntax (backslash
or colon or whatever) at the appropriate time.
Added SCHEME_KEYS to get rid of one hard-coded list of attributes (in
'select_scheme()').
Default 'install_path_file' to true, and never set it false (it's just
there in case some outsider somewhere wants to disable installation of the
.pth file for whatever reason).
Toned down the warning emitted when 'install_path_file' is false, since we
no longer know why it might be false.
Added 'warn_dir' flag to suppress warning when installing to a directory
not in sys.path (again, we never set this false -- it's there for outsiders
to use, specifically the "bdist_*" commands).
Pulled the loop of 'change_root()' calls out to new method 'change_roots()'.
Comment updates/deletions/additions.
Show how code can be written to handle __getslice__ & friends in a way that
is compatible with pre-2.0 versions of Python while still working with the
"new" way of handling slicing.
Additional explanation added by Fred Drake.
This closes SourceForge patch #101388.
"s#" will now return a pointer to the default encoded string data
of the Unicode object instead of a pointer to the raw UTF-16
data.
The latter is still available via PyObject_AsReadBuffer().
The patch also adds an optimization for string objects which is
based on the fact that string objects return the raw character data
for getreadbuffer access and are always single-segment.

of the Unicode object instead of a pointer to the raw UTF-16

flag is true, is set to a StringIO object that silently collects all
debug messages. This is triggered by the Node._debug=1 statement at
the top of test_minidom.py. After the tests, we better delete that
StringIO object to avoid wasting memory. We also reset the _debug
flag. (Note that this is an undetectable memory leak, and the memory
doesn't get collected by the cycle-gc either, because it's all
reachable -- it's just useless.)
data and default handlers -- a new reference was being passed to
Py_BuildValue() for the "O" format character; using "N" plugs the leak.
Fixed two other (minor) leaks that occurred on various error conditions.
Removed uses of the UNLESS macro, which makes code hard to read, and is
Evil.
Add support for parsing already-opened files. Make sure the parse()
method closes exactly those files that it opens.
Modified by FLD for better conformance to the Python style guide.
This closes SourceForge patch #101512.
Note a curious extension to the std C rules: x, X and o formatting can never produce
a sign character in C, so the '+' and ' ' flags are meaningless for them. But
unbounded ints *can* produce a sign character under these conversions (no fixed-
width bitstring is wide enough to hold all negative values in 2's-comp form). So
these flags become meaningful in Python when formatting a Python long which is too
big to fit in a C long. This required shuffling around existing code, which hacked
x and X conversions to death when both the '#' and '0' flags were specified: the
hacks weren't strong enough to deal with the simultaneous possibility of the ' ' or
'+' flags too, since signs were always meaningless before for x and X conversions.
Isomorphic shuffling was required in unicodeobject.c.
Also added dozens of non-trivial new unbounded-int test cases to test_format.py.
