# manual fixup:
# - 'end start' -> 'end'
# - 'mov edi, edi', 'lea ...' -> align
# - add 'near ptr' to some jumps
# - 'cmp     [ebp+edx+0], cl' -> 'cmp     [ebp+edx*1+0], cl'
# - 0FFxxh constants - masm treats a byte, ONLY sometimes prefix with 'word ptr'
# - jmp near:
#   - jmp _strchr
# - search for 'dword_xx+N', make byte/word, also word->byte
# - get rid of type propagation, regenerate as 'simple' var_
# - convert ds:0[eax*4] -> [eax*4+0] (h hotkey)
# - rm function chunks - they're funcs reached by tailcalls (usually)
