Pressing enter without anything selected should make popup disapear

[ptarjan]

When I type

class A

a popup helpfully appears offering me completions for A. If I just want to make a new class without choosing any selections, I have to press Esc which also takes me out of insert mode. In other popups that I'm used it by pressing <Enter> after the A the popup goes away and I am left with just the A I typed. Can I configure you do to that? I didn't see anything obvious in the docs.

I found the problem. It was with the suggested config. Removing inoremap <expr> <cr> pumvisible() ? "\<C-y>" : "\<cr>" made it work as I expected.
