Rearrange and better explain ksh syntax workaround
Move the rule setting the custom b:is_ksh variable used for this
workaround (established in 52615f6) into an ftplugin file, rather than
into ftdetect; the latter seems a much more appropriate place since by
this point we've definitely decided the file type is "sh".
From the revised comment in this changeset:
>Setting g:is_posix above also prompts Vim's core syntax/sh.vim script
>to set g:is_kornshell and thereby b:is_kornshell to the same value as
>g:is_posix.
>
>That's very confusing, so before it happens we'll copy b:is_kornshell's
>value as determined by filetype.vim and ~/.vim/ftdetect/sh.vim into a
>custom variable b:is_ksh, before its meaning gets confused.
>
>b:is_ksh as a name is more inline with b:is_bash and b:is_sh, anyway,
>so we'll just treat b:is_kornshell like it's both misnamed and broken.
>
>We can then switch on our custom variable in ~/.vim/after/syntax/sh.vim
>to apply settings that actually *are* unique to Korn shell and its
>derivatives.
