Save current buffer, cursor position and selection and execute f.
(args and kwargs) are passed as arguments to f. They indicate that any
number of parameters (named or unamed) can be passed in the usual way
to save_excursion, and they will be transparently passed on to f.
If undo_group is True, then all actions performed by f will be grouped
so that the user needs perform only one single undo to restore previous
start.
Then restore the context as it was before, even in the case of abnormal
exit.
Example of use::
def my_subprogram():
def do_work():
pass # do actual work here
save_excursion(do_work)
See also the with_save_excursion decorator below for cases when you
need to apply save_excursion to a whole function.
