Learn keys not saved to .mc/ini

[Alexander Kriegisch <Alexander Kriegisch name>]

I use mc 4.5.0 on an embedded Linux (Kernel 2.6, MIPS architecture) box,
i.e. on my DSL router. When logging into the box via SSH (putty client,
mostly) and using mc, a few keys are not working properly. The "learn
keys" feature works well insofar as it learns and uses the bogus keys
for the remaining mc session. No matter how often I save anything in my
user settings, the expected section for learn keys is always missing
from the ini file, consequently requiring me to re-learn keys for each
new session.

Is this a bug? It seems so to me. Is there at least a workaround which
forces mc to save those key bindings?
