Re: [PATCH 11/11] bug_fl(): add missing `va_end()` call

Jeff King [off-list ref] writes:

Being the curious sort, I ran it in a debugger. And indeed, "cp" is
filled with uninitialized garbage. The reason it works is that the test
calls bug() with a format string that does not contain any placeholders.
And thus our eventual call to vsnprintf() does not ever look at "cp" at
all!

;-)  Thanks.
