In almost all cases[1] you can have a trailing slash or not; there's no 
difference. I think that "ls" can be configured (somehow) to list 
directories with or without a trailing slash. It's all about preference.

[1] As usual, there are messed-up exceptions. I've noticed that when I use 
"ls -ld" on symbolic links that point to directories, the result is 
slightly different depending on whether I include a trailing slash.

Yes, that's sum total of the relativity of symbolic links.
