Re: texi2dvi: fix support for whitespace in working directory

[Karl Berry]

    You cannot expect bash behaviour then.

It's bourne behavior not bash behavior.  As you know, we go to great
lengths to avoid bash dependencies in texi2dvi (and in all other core
GNU shell scripts).

However, as I recall, there is a bug in some versions of bash that
require
  case "$foo"
instead of
  case $foo
So that could be the culprit.

The second hunk should definitely be a no-op.  All shell code everywhere
in GNU (autoconf, etc.) depends on
foo=$bar
being handled correctly (no word expansion of $bar).

Or else something unrelated also changed.  -k
