This line is overly long.  Let AsciiDoc wrap it upon output and keep
the source within a reasonable limit (see existing lines around the
new text to see what is considered reasonable).

Do I see too many dashes before the option name, by the way, or is
it my e-mail client tricking my eyes?

Hmm, we'd be better off not having a bare UTF-8 sequence in the
source like this, especially when you already have the same thing
backslash-escaped in the "expect" file below.  Perhaps

	NAME="a-\303\244_o-\303\266_u-\303\274.txt" &&

	UTF8=$(printf "$NAME") &&
        CP1252=$(printf "$NAME" | iconv -t cp1252) &&
        echo "\"$UTF8\"" >expect &&

        >"$CP1252" &&
        p4 add "$CP1252" &&
        ...

or something along that line?
