all: clean up misleading indentation warnings

Misleading indentation warnings are actually useful, as they
will occasionally reveal actual bugs (cf the apple `goto fail`
security bug from a few years ago).  Newer versions of clang
(at least) are more aggressive about warnings in this regard,
which has exposed a few warnings that are annoying.  However,
they are easy to address.
