[PATCH] ls: Use pretty UTF-8 arrow when showing where symlinks point to

[Lennart Poettering]

Diego Pettenò complained that "ls -l" doesn't use the UTF-8 arrow
character to show where symlinks point to. This tiny patch fixes that.
With this applied the character is used when the CODESET is UTF-8
otherwise we fall back to the traditional "->" arrow.

Ah, "ls -l" is so much prettier now with this oh-so-important patch! 
For verification:

This will of course break scripts that try to parse the output of "ls
-l" and look for "->". But quite frankly those scripts are broken
anyway and should be using "LC_MESSAGES=C" or suchlike. One could
argue this breakage might even be desirable.
