MerlinRename binding messes with search register in vim

[nilsbecker]

here is the mapping i am using:

au FileType ocaml nmap <buffer> <localleader>r <plug>(MerlinRename)

i see the following behavior: i first search for an identifier name fmt with /fmt . after i find one, i want to rename it with MerlinRename.

typing :MerlinRename ff correctly renames the identifier fmt to ff and has no unwanted side effects.

however, when i instead invoke the binding \r, the identifier is renamed but also, the search register now contains the value 2, as evidenced by pressing n for the next match, which finds the next occurrence of 2 in the file.
