2b0186fd58 boot: make routine field 1b
I forgot to do it earlier. NOP having an opcode of 0, it didn't have
any effect.

d2ec5e271c Optimize boot binary's word execution code
Should be significantly faster now. Less push/popping and usage of
DE instead of IY.

b73e1a5f7a z80a: invert the meaning of IFZ, IFNZ, IFC, IFNC,
It is much less confusing when "IFZ," means "If Z is set, continue
into IF, else, jump to THEN,".

add3b6629b Make DO .. LOOP binary code more compact
Only a few bytes saved in forth1.bin, but the DO .. LOOP construct
isn't used much yet. It's still significant savings per LOOP call.

d0545d555f upload: use A! instead of C!
It makes the tool much more versatile. I'll have adev being included
in all recipes, so it can be assumed.

d08a9711c5 boot: make HERE point to RAMEND instead of CURRENT
The former was only used in the peculiar context of "/emul". The
regular case is actually HERE pointing to RAMEND on boot.

420836276d readln: rename (c<) to (rdln<)
so that it isn't picked up automatically at boot. Only when (c<$) is
called do we override (c<). This fixes tricky boot problems.
