I guess it is not `when`, but `\`. It was a known issue arised because in
collection `[\[]' there are two characters: `\` and `\[`, not one `[` which is
weird (but described in POSIX). I have wrote a patch for this, but sended it
only to vim-dev mailing list, not to all maintainers of all scripts that have
this error (there were way too many scripts and too many maintainers).
