Nicholas Nethercote 423bf4233d Rename the span args to emit_unescape_error.
The `span` arg is described in a comment as "interior span of the
literal, without quotes", which is incorrect. It's actually the span of
the error part of the literal, corresponding to `range`.

This commit renames `span` and `span_without_quotes` to make things
clearer, and fixes the erroneous comment.
