Well spotted; thanks for reporting it!
The plural options work! So flag-reference.html should be corrected.
In actual fact the flag reference was exactly right, except the flags
could take any argument, which they then ignore (so the "s"s were being
treated as an argument when you gave the flags as plurals).
This meant that things like "-keep-s-file=no" would also result in the
.s file being kept, so I've changed the code to accept only
-keep-foo (makes sense when using ghc -c) and -keep-foos (makes sense
when using ghc --make). -keep-tmp-files is still plural-only.
Everything should be consistent now.
Just FYI, historically, these flags were called -keep-hc-file-too,
-keep-s-file-too, etc. When I rewrote the driver I made it ignore the suffix,
so that I could shorten the flag names and keep backwards compatibility. I
don't think anyone still uses the old names.
Cheers,
Simon
