%.*s precision supposedly takes an int, according to gcc

* remove uneeded remains of r750126.

Accelerate mod_dumpio processing; * drop a frequent query for the mod configuration (pass as f->ctx) * drop one copy, at least for ASCII and ensure larger buffers are logged in their entirety. Some clarity in output can be added by designating continuations vs first lines.

For correct dumping, translate data from ASCII
