sh: handle backspace in readline; prompt is now '#'
readc() returning $08/$7F now drops the last char from the command buffer
(and emits one $08 so the terminal erases it) instead of storing the raw
byte. Previously "lz<bksp>s" left the buffer as "lz\x08s", so the command
"ls" was reported "not found" even though the screen showed "ls".
Also change the shell prompt from '$' to '#'.
osk: B button types the selected key SHIFTED (uppercase a-z). A types the
key as shown (lowercase/digit/symbol); B on a letter subtracts 32 for the
uppercase glyph (the font already has A-Z). Non-letters are unchanged.
