Package: ksh
Version: 93u+20120801-2
Severity: normal
I get the following error:
$ cd ""
ksh93: cd: bad directory
which is incorrect according to POSIX:
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/cd.html
See Step 5:
5. Starting with the first pathname in the <colon>-separated
pathnames of CDPATH (see the ENVIRONMENT VARIABLES section) if
the pathname is non-null, test if the concatenation of that
pathname, a <slash> character if that pathname did not end with a
<slash> character, and the directory operand names a directory.
If the pathname is null, test if the concatenation of dot, a
<slash> character, and the operand names a directory. In either
case, if the resulting string names an existing directory, set
curpath to that string and proceed to step 7. Otherwise, repeat
this step with the next pathname in CDPATH until all pathnames
have been tested.
So, in general, this should change to the first directory of CDPATH,
and if CDPATH is null (giving the case "If the pathname is null"),
this means the current directory ".".
ksh93 seems to be the only shell that behaves that way, the other ones
behaving as expected.

Closing since in the operands section it is said
If /directory/ is an empty string, the results are unspecified.
