I do not like this.

This may be acceptable. I'm not sure if there are components files that depending on the caching, even after %(lit) is used. > The first one is easy, but might have unintended consequences. Agreed. > The second > is more complicated, but not terrible and is arguably more correct. Thoughts? My question is: If the str buffer is zeroed, or set, via %(lit), should the cache be automatically cleared? --ewh _______________________________________________ Nmh-workers mailing list Nmh-workers@nongnu.org https://lists.nongnu.org/mailman/listinfo/nmh-workers
