FIXED: do not trim names that start with a space

[warpdesign]

If filenames started with a space (which is a valid name in Unix), these spaces would be removed from the returned listing, returning.

For example:

--rw-r-----   1 userName alternc       460 Aug 22 03:45  test1
--rw-r-----   1 userName alternc       560 Aug 22 03:47   test2

Would return two wrong names: "test1" and "test2" instead of " test1" and " test2".

I added a new test for this particular case.
