Not given our implementation. The buffer efficiency argument is for other kinds of parsers that are not reading just one line at a time. > If not, then stripping trailing whitespace from the line prior to obs-fold and > eating all leading whitespace on the obs-fold line will result in a single SP > character, which should be just fine unless spaces were significant within > a quoted value.

Note that obs-fold has been formally deprecated outside of message/http. We can remove its handling at any time we are willing to accept the risk of strange error reports. I do not believe it is part of our versioning contract. ....Roy
