This analysis isn't correct, and the description above describes the
correct behavior.  A backslash in the expansion of a variable does not
have any special meaning to word splitting.  Backslashes are special to
the shell parser; if you want to have them interpreted, you need to run
the text through the parser.  This is usually accomplished using `eval'.
