Title: Remove zero-width spaces

There exist some zero-width spaces[1] in a source file.
They are harmless because in comments, but a little bit uncomfortable.

Maybe it's hard to see from the diff, the output passed to `less` in
my environment is as follows:

```
$ git --no-pager show | less

Also, I grep'ped non-ASCII characters in repository [2] and
other than above are ones from binary files or intentional ones.
