annotate Python/compile.c @ 18065:889db6d55506 legacy-trunk

SF bug 430991: wrong co_lnotab Armin Rigo pointed out that the way the line-# table got built didn't work for lines generating more than 255 bytes of bytecode. Fixed as he suggested, plus corresponding changes to pyassem.py, plus added some long overdue docs about this subtle table to compile.c. Bugfix candidate (line numbers may be off in tracebacks under -O).
