At least 5 templates (including the one discussed in this thread), approx
160 transclusions on yue.wp, mostly in article space. That means 0.25% of
all articles.
According to the discussion, zh.wp is affected by this bug too: at least 7
templates, according to my insource search.
en.wp has at least 45 pages with this problem, including 9 templates.
[[en:Template:Merge to]] alone has 3000+ transclusions.
Since this change affected [[en:Template:Merge to]] which is a trunk
project copied by many other wikis, I expect a very large - probably in the
tens of thousands - total number of broken pages.
My insource search string:
insource:/"[[:{{NAMESPACE}}:"/
