I think this is just a case of different terminal emulators doing things differently, since this kind of behaviour (along with a lot of other terminal details) is not specified in any authoritative standard. The termcap/terminfo databases try to document which terminals support something like this in the auto_left_margin/bw variable (see first entry at http://www.tldp.org/LDP/lpg/node127.html), but I'm unsure of how accurate these are here (they cannot be for terminals making the behaviour configurable). As a developer of a terminal emulator (Termux), I think the behaviour with backspace across newlines that the PicoLisp REPL expects is a sensible one and is planning to introduce that behaviour there, so it will at least work in one more terminal soon :). A general solution working across more terminals would involve either pulling in something heavyweight like readline/rlwrap as already mentioned, or extending the REPL to use escape sequences to move the cursor across lines without depending on backspace.
