cleanup: avoid _ for local unused tmp variables - that is reserved for i18n

_ is usually used for i18n markup but we also used it for I-don't-care
variables.

Instead, name don't-care variables in a slightly descriptive way but use the _
prefix to designate unused variable.

This will mute some pyflakes "import '_' ... shadowed by loop variable"
warnings.
