This is not "trivial" nor "style fix", though.

It is not "trivial" because it also changes the behaviour.  Instead
of resetting the strbuf each time after the loop body runs, the new
code resets it before the loop body, even for the 0-th iteration
where the strbuf hasn't even been used at all.  It is not a "style
fix" because we do not have a particular reason to avoid using the
comma operator to perform two simple expressions with side effects
inside a single expression.

This one is a style fix that is trivial.  It does not change the
semantics a bit, and we do prefer "else if" to be on the same line
as the closing "}" of the earlier "if" that opened the matching "{".
