direxpand in 4.3 is different from in 4.2

[Clark Wang]

For example in 4.3 when direxpand is enabled, `cd ./tmp<TAB>' would be
expand `./tmp' to the full path (e.g. `/root/tmp/'). I think this is not
good especially when the full dir path is very long. Bash 4.2 (tested with
4.2.37) does not behave like this. Could we keep the 4.2 behavior?

This isn't accurate. When you build bash-4.3 with the default options, and
choose to enable direxpand using shopt, you get the same behavior as in
bash-4.2. In particular, relative paths aren't expanded to full paths.

If, on the other hand, you build bash with the enable-direxpand-default
configuration option, you do get this behavior. I left the relative-path
expansion option enabled when bash is built this way. In retrospect, I
should probably have left it out. If you prefer it disabled, you can
change the assignment to dircomplete_expand_relpath in bashline.c.

That is not to say there aren't problems with relative paths and completion
in bash-4.3, but they aren't with direxpand. Additionally, I'm not talking
about the situation when bash-completion is included in the mix.
