`rm *` count is incorrect with `setopt GLOB_DOTS`

[zsh-workers@xxxxxxxxxxx]

Hello,

When I run `rm *`, zsh asks if I "want to delete all x files", where x 
is the number of files to be deleted. However, with `setopt GOB_DOTS`, 
this number appears to be two more than the actual number of files.

$ zsh -f
% cd $(mktemp -d)
% touch foo bar
% rm *
zsh: sure you want to delete all 2 files in /tmp/tmp.cLNHQwcBW1 [yn]? n
% setopt GLOB_DOTS
% rm *
zsh: sure you want to delete all 4 files in /tmp/tmp.cLNHQwcBW1 [yn]?

I'm testing with zsh 5.5 on Arch Linux. I also reverted back to zsh 
5.3.1, and this issue was still present. However, I get the feeling that 
this issue wasn't around since that long ago, so the source of the 
problem could be something else (apologies in advance if it is).

Cheers.
