color: allow for user-configurable terminfo codes for effects If the entry in the terminfo database for your terminal is missing some attributes, it should be possible to create them on the fly without resorting to just making them a color. This change allows you to have [color] terminfo.<effect> = <code> where <effect> might be something like "dim" or "bold", and <code> is the escape sequence that would otherwise have come from a call to tigetstr(). If an escape character is needed, use "\E". Any such settings will override attributes that are present in the terminfo database.

update: warn if cwd was deleted During update directories are deleted as soon as they have no entries. But if current working directory is deleted then it cause problems in complex commands like 'hg split'. This commit adds a warning that will help users figure the problem faster.

parsers: avoid PySliceObject cast on Python 3 PySlice_GetIndicesEx() accepts a PySliceObject* on Python 2 and a PyObject* on Python 3. Casting to PySliceObject* on Python 3 was yielding a compiler warning. So stop doing that. With this patch, I no longer see any compiler warnings when building the core extensions for Python 3!
