Subject: [Bug] S-flag imposes non-greedy match where it shouldn't
To: Zsh hackers list <zsh-workers@zsh.org>
Content-Type: text/plain; charset="UTF-8"

Hi,
str="aXXXXXbXXXXc"; print ${(S)str##X##}
Output: abXXXXc

As it can be seen, the flag worked correctly. However, when %% will be
used instead of ##:

str="aXXXXXbXXXXc"; print ${(S)str%%X##}
Output: aXXXXXbXXXc

Then the (S) flag seems to impose also non-greedy matching, not only
substring searching.
