The braille and block renderers were two near-identical awk programs
sharing a verbatim PBM tokenizer, header check, and blank-line trim,
differing only in the per-cell rendering. One awk with a mode variable
now branches where they actually differ.
The option surface served two in-repo callers, both passing constants:
the duplicate positional loop behind --, the undocumented --block and
--braille aliases, and the --flag=value forms all go. The two magick
probes for the alpha range collapse into a single invocation.
Output is byte-identical across images and flag sets for everything
that remains, including both real callers' exact invocations.
