I don't disbelieve it.

I see PWS already replied, but:  It appears to me that to compute outcs
it's necessary to unmetafy the line in the MULTIBYTE_SUPPORT case, so we
are probably stuck with your patch from 28941.

} Otherwise we have to copy zlemetaline first and then run
} stringaszleline, and discard all that work, which seems silly.

It'd probably be possible to write a routine that decodes metatifed
characters on the fly and counts what they decode to, without updating
the buffer in place, but that's not what's available now.
