When local state_descr is needed?

[Marko Myllynen <myllynen@xxxxxxxxxx>]

Hi,

It's a bit unclear to me when local state_descr should be declared.
Reading the man page makes me think that it certainly doesn't hurt to
do it especially when using the ->string convention but is it in fact
needed then to avoid any potential or concrete side-effect?

For example, does the patch below matter in practice at all or not?
In the file later on there is:

  "(-f --from-code $exargs)"{-f+,--from-code=}'[specify code set of input file]:code set:->from_codeset'
  "(-t --to-code $exargs)"{-t+,--to-code=}'[specify code set for output]:code set:->to_codeset'
