I've been programming Python with Vim for a while but one thing I haven't been able to figure out how to do it set it to auto indent to the level of the last open paren.
According to pep8 if you have an open paren and you need to break the line to fit in 80 columns then you're supposed to continue the next line at that open paren. Example:
calling_some_really_long_function(that, has, way, too, many, arguments, to, fit,
on, one, line)
Ydgrasil seems to have a modification for the
.vim/indent/python.vim file that will do just this.
