- Subject: The shortest possible sequence match with Lua regular expressions

I ran into this today, and while I tried to explain it away, I have to
admit I am mildly confused.
Why does the following match the entire string "/dev/myprog/image/xyz/"?
The documentation states that a - (minus) matches the shortest possible
I hadn't given this any thought until today, as I normally would have
written '.+(/.-/)$'. That would have yielded the correct result of
'/xyz/'. When discussing it with a coworker, though, he raised the
point that with the final / (slash) anchored at the end of the string,
the shortest possible matching sequence should be '/xyz/'.
I can buy into that argument. What are we missing?
