This is the correct behavior.  It is required by POSIX - dirname is a
completely textual operation that pays no attention to what exists or
does not exist in your file system, and the dirname of a string that
resembles a relative file name is the string '.' (the current directory
is the correct dirname of a relative file name, if that relative name
was indeed a file; but the algorithm works even if there is no file by
that name).

I'm closing this bug report, as there is no bug here.  However, feel
free to make further comments if you need more clarification, or help in
determining if 'dirname' really is the best fit for the shell scripting
task you were really attempting to solve.
