Finding with ? renders / in the status bar instead of ?

[dsschnau]

When you search forward with /, a / and your search term appears in the status bar on the bottom:

But if you search backwards with ?, the same / is displayed (the actual backwards searching with n and N works as expected). What should display instead in the search bar is ? followed by the search term.

To Reproduce
Steps to reproduce the behavior:

1. From normal mode, type ?, then a few characters to search for.
2. That's it. A / with your search term appears in the status bar.

Expected behavior
What should display instead in the search bar is ? followed by the search term.
