- Change PREFIX to PREFIXES, which contains a sequence of prefix strings.
  This is useful since we want to look for both Py and PY.
- Wrap a long line.
- Collect struct tags as well as typedef names.  Since we generally only
  use one of the other, that improves coverage.
- Make the script executable on Unix.

This could use a better approach to determine if a symbol is documented,
and could easily avoid keeping the massive string in memory.  That would
take time to actually write more code, though, so we'll bail on that
for now.

vgetargskeywords():  Now that this routine is checking for bad input
(rather than dump core in some cases), some bad calls are raising errors
that previously "worked".  This patch makes the error strings more
revealing, and changes the exceptions from SystemError to RuntimeError
(under the theory that SystemError is more of a "can't happen!" assert-
like thing, and so inappropriate for bad arguments to a public C API
function).

fixes the problem reported in SF bug #477023 (Jonathan Mark): "pdb:
unexpected path confuses Emacs".

ZipFile.__del__():  call ZipFile.close(), like its docstring says it does.
ZipFile.close():  allow calling more than once (as all file-like objects
in Python should support).

pass the buffer length.  Stop using it.  It should be deprecated, but too
late in the release cycle to do that now.
New static format_float() does the same thing but requires passing the
buffer length too.  Use it instead.

Also change all the helper functions to pass along the size of the
msgbuf and use PyOS_snprintf() when writing into the buffer.

const char* instead of char*.  The change is conceptually correct, and
indirectly fixes a compiler wng introduced when somebody else innocently
passed a const char* to this function.

seterror() uses a char array and a pointer to the current position in
that array.  Use snprintf() and compute the amount of space left in
the buffer based on the current pointer position.

If it returns -1 (which indicates overflow on old Linux platforms and
perhaps on Windows) or size greater than buffer, write a message
indicating that the previous message was truncated.
