Since the introduction of the 'calln' macro, the 'call1', 'call2', ...,
'call8' macros are just aliases for the former.  This is slightly
misleading and potentially unhelpful.  The number of arguments N can
also easily go out-of-synch with the used alias callN.  There is no
reason not to replace these aliases with using 'calln' directly.

To reduce the risk for mistakes, the tool Coccinelle was used to make
these changes.  See <https://coccinelle.gitlabpages.inria.fr/website/>.

* src/intervals.c (set_intervals_multibyte_1):
Add an eassume to pacify GCC.  Deparenthesisze.

This is a refactoring.  It eliminates a few unnecessary conses and
allows for further improvements.

(print_prune_string_charset, print_object, print_interval):
Pass a pointer to a Lisp_Object instead of a Lisp_Object.

When `total_length` is 0 there should be no subtree at all, but
`delete_interval` only deletes one interval, so make sure we don't end
up with some stale child of `i`.
