Brace layout, comment layout and indentation are all brought into line
by pg_indent, which Bruce runs at least once per release cycle.
However, I don't think pg_indent will consider breaking non-comment lines
into multiple lines, so it's up to the code author to be reasonable in
that area.
My own practice is to try to make the code look nice in an 80-column
window.
BTW, if you are writing a comment that you don't want to have
reformatted by pg_indent's rather braindead reformatter, protect it
with some dashes:
/*---------- * This text will not get reformatted. *---------- */

Not very much. You have to be particularly cautious about removing
system-header #includes, since what looks redundant on your platform
may not be redundant for other platforms. I think Bruce has a tool
to look for unnecessary includes of our own header files, but it
doesn't risk trying to remove system headers.
