folding.el 2.93 : questions for merging into text-modes package

it'll probably be at least a few more days before a diff is submitted, to merge the new beta version of folding.el (2.93) into the text-utils package. a question: It'll take quite a few calls to #'define-obsolete-{function,variable}-alias, to make sure that the code which uses the current xemacs folding.el will work with the newer version. Should there be a seperate file, e.g.: folding-dep.el, for that? If they were, folding.el could have one simple line added to it: (load-library "folding-dep") to ensure that old init files will be compatible with the current folding mode. But, i don't have write access on the xemacs cvs server, nor am i sure if i'm ready for it, so the diff submitted, for the merge, would include a modified folding.el -- not the original code. Would that still be acceptable, under licensing terms? -- sean
