Log Message:
Re-process (not discard) invalid bytes in command strings
When a byte outside the allowed command string range (ECMA-48 §5.6)
appeared inside a DCS, OSC, APC, or PM string, both the string and
the invalid byte were silently discarded. The discard behavior was a placeholder from before string processing was implemented (c99f9885).
Now the malformed string is discarded but the invalid byte is
re-processed as normal input (e.g., BEL beeps, FF clears screen).
Added 4 tests: OSC+BEL, DCS+BEL, APC+SI, SOS+SOS.
Documented the behavior in cterm.adoc.
Added comment documenting the SOS frame invariant in STS readback.
