OS X: Nonexistent path in query output

[dturner-tw]

To repro:

git clone https://github.com/torvalds/linux
cd linux
watchman watch .
sleep 15 #or so -- until watchman is finished loading up the initial state.
watchman -j < query1
find . -name 'u*.c'|xargs sed -i '' 's/memory/forget/g'; sleep
1;watchman -j < ~/query2

query1 and query2 are the same but for the "since" field. You can use any value for since for query1, but query2 should use the "clock" field from the output of query1. Here is the query:

["query", "/Users/dturner/linux", {"expression": ["anyof", ["type",
"f"], ["type", "d"], ["type", "l"]], "since":
"c:1421691971:94141:1:222", "empty_on_fresh_instance": true, "fields":
["name", "exists", "ctime_ns", "mtime_ns", "size", "uid", "gid",
"ino", "dev", "mode"]}]

The bug is that the output contains entries like
arch/hexagon/mm//Users/dturner/linux/arch/hexagon/mm/.uaccess.c.15532

Of course, there are no files by that name. It looks like a full path is occasionally being concatenated instead of a filename.
