When splitting IMAP messages in Gnus' nnimap, there is a defvar called `nnimap-split-download-body-default', which is consulted to decide whether to download the whole message body during splitting, or only consider its headers. It appears that there used to be a defcustom called `nnimap-split-download-body', which was advertised to the user, and this defvar was used to hold... its default? It's odd. In 2010, in commit 20a673b2d, a bunch of external Gnus code was merged in, changing a lot of nnimap.el, and in the course of that the defcustom was deleted. The defvar still remains, and is still effective. The manual still refers to the customization option. This looks unintentional, and I'd like to apply the attached diff, restoring `nnimap-split-download-body' as a user option, and getting rid of the default variable, which seems unnecessary. If this seems okay I'll do up a proper commit, and make sure the documentation is all accurate. The same user who reported this also expressed a desire to be able to download message bodies conditionally, based on the headers, only if a split rule required it. I'm not at all sure about the feasibility of that, but wanted to see if anyone else had an opinion. Eric
