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.
