[Message part 1 (text/plain, inline)]
How to demonstrate the bug:
$ cd ~
$ /bin/pwd
/u/home
$ mkdir -p this/is/a/test
$ export CDPATH=:~
$ cd this/is/a/test
$ emacs -Q
launch 'eshell'
prompt should read "~/this/is/test $"
type "cd .." at the prompt.
prompt reads "/u $".and /bin/pwd results in "/u"

This is interpretation of CDPATH is not the same as that of BASH or of  of
EMACS prior to 24.2.91 that both treat NULL components of the colon
separated list of values as ".".  See, bash(1) discussions of CDPATH.

This is due to the changes in http://debbugs.gnu.org/12351 .

Before:

(parse-colon-path ":~")    ->  (nil "~/")

After:

(parse-colon-path ":~")    -> ("~/")


We shouldn't be deleting nil from the result.
