Also, can you resubmit with diff -U99999? With svn: svn diff -x -U99999. With git: git diff -U99999. This will improve context.

My original email was incorrect. This should be setup_buffer_bufsiz instead.

+ 5 should always be the same as second argument to setup_buffer(). It is now but it should be a macro to ensure they are the same, avoiding someone changing one and not the other.

Can the 2 here be # defined or added to one of the other sizes so that it's not a "magic number" ?

Why +2? Why is it not a part of addlen?

Eliminated magic numbers according to George's advice.
