<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Rather than cramming as much as you can into a single statement, why not keep the separate statements like it was before?
Remember the KISS principle.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I initially had it the other way. To me this was clearer that we are saving a ref specifically for this function call. Although I still prefer this way, if you feel strongly about it I can change it.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I have had to fix a few places in Asterisk where the assignment was crammed into the if test and the parentheses were misplaced.
if ((a = b < 0))
when it should have been
if ((a = b) < 0)
Breaking the assignment and test into two statements avoids the problem altogether. It also gives better places to break long lines.
Although C is not lisp, you can still get Lost In Stupid Parentheses. :)</pre>
