[EDIT: Actually, 8 of the commits top of tree as of writing are "...". wow.]
On top of that, "Second effort to sanitize input string" at [1] appears related to this issue, and doesn't have a single test change, even on the second attempt!
[1]: https://github.com/ImageMagick/ImageMagick/commit/a347456a1e...
While I was at it, 49 commits using "..." as the message, and 8520 commits with absolutely no message at all.
Maybe github is just a mirror
(edits - nope, looks like they changed recently. perhaps it's a reflection of developers moving from svn to git)
