1. It depends on instrument and style.
2. What about
{ c4( c) c( d) | e( d) c2 }
or
{ c4( c c c) }
?

A slur definitely is semantically different from a tie, so it’s 
important to keep them apart. Though certainly there are cases where 
it’s impossible to tell.
In Andrew’s first example it’s unlikely that the cis is supposed to be 
struck twice (even more now we know that it’s piano music) so I suppose 
a tie is the way to go.
