This action is completely valid on both Windows and Linux (and OS X)
operating systems; tested with `mklink` and `ln -s` respectively.
Note that targets for hard links must exist, thus we check specifically
for symbolic links.
Both the path globber in session state and the `New-Item` implementation
needed to be fixed to allow the target not to exist.
Resolves#801.
Also enable symbolic link tests on Windows.
The aliases which conflict with Linux native commands were consolidated
and removed with the pre-processor definition `LINUX`. Additionally,
several "conflicts" are purposefully kept and likewise consolidated.
They are kept because Bash itself stomps on the native commands with its
own built-ins, and so we're adopting the same behavior.
The `clear` and `more` aliases are edge cases where the functions they
call are already fixed for Linux, and so we keep these too.
Resolves#567.
