-o and --dvi

[Karl Berry]

Running
  makeinfo -o cppline.out --dvi  cppline.tex
ends up running texi2dvi on cppline.out, instead of cppline.tex:
  This is pdfTeX, Version 3.1415926-2.3-1.40.12 (TeX Live 2011)
   restricted \write18 enabled.
  entering extended mode
  (./cppline.out)
  *

Adding --debug, as in:
  makeinfo --debug=-1 -o cppline.out --dvi  cppline.tex
causes TeX to be run on cppline.tex.  The debug line is:
  texi2dvi|--debug|-o|cppline.out|--dvi|cppline.tex
which looks right.  Something is awry.

(Didn't know if this was the same thing as in the other message, so
sending separately.)

Thanks,
