"read -S" Unknown option

[BebeSparkelSparkel]

Looking at the read doc read -S is supposed to be the same as --shell. However for me, read --shell works but -s does not. This does seem to be a regression.

-S or --shell enables syntax highlighting, tab completions and command termination suitable for entering shellscript code in the interactive mode. NOTE: Prior to fish 3.0, the short opt for --shell was -s, but it has been changed for compatibility with bash's -s short opt for --silent.

I think that was me. I was bit by the duplication of values for the two separate getopts arrays.
