Discovered while trying to debug a template of [[plunky]]'s:

When web-editing a template, clicking "Save Page" always results in ikiwiki thinking a page-editing conflict occurred. It's not related to HTML::Template tags, because I can put a template's contents into some other page, verbatim, with no errors.

Joey and I can't reproduce with a git-backed wiki. It's probably a bug with the CVS backend. He suggests two possibilities: 

7. `cvs commit` is really failing
7. `rcs_commit` does not return `undef` when it does `return unless cvs_is_controlling`

> Something odd happened to me just now, web-editing [[wiki/todo/hook_up_wiki_commits_to_www-changes@]] with SPNEGO. I added a line, clicked Preview, then clicked Save Page and got the spurious conflict. However, after clicking Cancel, the edit was indeed there. This may or may not be the same problem.

>> And the same thing happened to the above edit. Now trying `kdestroy` and plain HTTP auth.

>>> There were two reasons `cvs update` wasn't silent: the `blog` directory where ikiwiki's aggregator stashes blog entries, and a "note" template marked for Add but not yet added. I've added the former to `.cvsignore` and committed the latter. Will this web edit be spurious conflict-free?

>>>> Yes, it was. That narrows it down a bit for when I've got time to fix this properly. --[[schmonz]]

>>>>> Very likely caused by the CGI not running [[setgid `netbsd`|done]] until now. --[[schmonz]]
