_getcwdux() return the cwd including the drive name when a buffer is passed

[komh]

Hi/2.

Describe the bug

_getcwdux() should return the cwd excluding the drive name all the time. However, it returns the cwd including the drive name when a buffer is passed. It works as expected when NULL is passed.

To Reproduce

See https://github.com/komh/klibctest/blob/master/io/_getcwdux-1.c

Expected behavior

_getcwdux() should return the cwd excluding the drive name even if a buffer is passed.

Here is the patch:

Subject: [PATCH] _getcwdux: Fix _getcwdux() return the cwd including the drive
 name

_getcwdux() should always return the cwd excluding the drive name.
However, it returns the cwd including the drive name when a buffer is
passed. It works as expected when NULL is passed.
