Handle multiple breakpoints at same line. Update docs/test.
Patch by Xavier de Gaye.

Amaury noticed that this was originally written in a way that would fail on
names that can't be encoded with the mbcs codec. Restructured the function
to work with wide names first then narrow names second, to fall in line
with the way other functions are written in posixmodule.c.

Approved by Guido (BDFL) and Georg (RM).

Remove parenthetical remark that is confusing now that the module is not named "__builtin__" anymore.

Issue #7094: Add alternate ('#') flag to __format__ methods for float, complex and Decimal. Allows greater control over when decimal points appear. Added to make transitioning from %-formatting easier. '#g' still has a problem with Decimal which I'll fix soon.

'typecode' is always an ascii letter, there was no data lost.

Issue 2986: Add autojunk paramater to SequenceMatcher to turn off heuristic. Patch by Terry Reedy, Eli Bendersky, and Simon Cross
