Slightly annoying helm behavior

[Kendall Shaw]

I suppose this is not a bug and it's a strange case. But, it's
confusing and maybe worth noting.

If I have 2 files in a directory:

something.cfg
another-something.config

and I attempt to rename something.cfg to something.config, helm
suggests the existing file another-something.config as the target name.

If I were used to overwriting files while doing some task, I might
accept the suggestion and say yes to overwrite, not noticing that I
have just clobbered a different file than I expected.
