Sorry. It's always been there.

Actually, I am discouraged that applications were not written to use the
portable `printf'. Use of `echo' in portable applications has been
deprecated for years.
It's hindsight, of course, but had mc been written (or modified later)
to use printf, it would not need the shell-specific code it apparently
now contains.

The standards evolve, and bash evolves with them. Previous editions of
POSIX moved from "nothing, but if the first argument is -n, the results
are implementation defined" to "no options, but the interpretation of
backslash characters in the arguments is implementation defined", to "no
options, and you have to interpret this set of backslash escapes for XSI
conformance". The final (current) set of conditions is what the POSIX
conformance test looks for.
