INSERTION_POINT.
Attempt to handle formatting: if INSERTION_POINT is the first thing on
its line, and INDENT is sufficiently sane, then add CONTENT on its own
line, using the indentation of INDENT.
Otherwise, add CONTENT directly before INSERTION_POINT.
For example, adding "CONTENT;" with the closing brace as the insertion
point and using "INDENT;" for indentation:
if ()
{
INDENT;
}
would lead to:
if ()
{
INDENT;
CONTENT;
}

if () {INDENT;}
would lead to:
if () {INDENT;CONTENT;}
