I don't believe the theory that the fault lies there.  If the flex
rules were taking the backslash-embedded-in-a-shift-JIS-character
as a backslash, they would think it is the start of a new backslash
command, with the result being that the filename argument gets
truncated there.  That doesn't match the reported symptoms: we
see more of the filename than that echoed back in the error message.
So I think the filename is getting through that part just fine,
and then we're messing it up in canonicalize_path or adjacent
processing.
