} Do you have a reference where "character" is defined? This behaviour
} is the same in posh and dash:

I thought this was discussed on the austin-group list but I can't find a
search term to dig it out of the archives.  (I did find the thread about
${##} as a side-effect of the attempt.)

On my Ubuntu 12.04 system, /bin/sh is a link to dash, so zsh invoked
as sh behaves like /bin/sh.  On CentOS, /bin/sh links to bash, so they
behave differently.
