While fixing one of the affected packages, I discovered that it was
using similarly problematic syntax to act as a strcat replacement of the
form 'sprintf(buf, "%s\n", buf)', which that regexp didn't catch. I
can't imagine that's a common mistake, but it's easy enough to match on
pcregrep -M 'sprintf\s*\(\s*([^,]*)\s*,\s*"%s[^"]*"\s*,\s*\1\s*[,)]'
All pending upload, thanks.
