After re-reading the above, I realize that my statement may have
sounded a lot stronger than I intended it to.  If our codebase
allowed decl-after-stmt, that would change the equation and a
different style might help readability somewhat.

If decl-after-stmt were allowed, the group of lines that declare
variables at the beginning before the real logic begins do not even
have to be there, and "if some variables have initialization that
involve program logic that need to be read carefully, the
declaration at the beginning no longer can be coasted over as
boilerplate" complaint disappears.  The entire block can become the
logic, declaring variables as necessary at the point they are
required, without having to have a separate decl at the beginning.

Note that I am not advocating to allow decl-after-stmt; I do not
think the imagined readability benefit is worth it.
