Playground needs godoc to support calls to /vet endpoint in playground.js.
Optional parameter "vetEl" is added to the function "playground".
If it's passed then the js installs the click handler to the element.
There is a corresponding CL 100776 for the playground code.

The semantics of this change are that the last line will be subsituted

Previously we would spin up a new goroutine for every directory
we needed to parse. Since parent directories cannot exit until
children have exited, in large GOPATH directories we could have 8000+
goroutines evaluating directories concurrently. The race detector uses
tsan, and tsan can handle a maximum of 8192 concurrent threads at one
time.
Limit the number of concurrent threads. It is difficult to do this
in a way that does not involve a child being blocked on a parent
completing to spin up goroutines for itself to complete. Solve this by
completing work on the main thread if there are no additional workers
available to help complete work.
I was expecting limiting the concurrency to hurt performance, but it
actually significantly improves it. Benchmarks were performed using CL
94904 at tip, and with goroutines at 2, 4, and 8 times the number of
CPU's.

This regression is due to https://go-review.googlesource.com/c/go/+/100235
which made the go/scanner behavior match the compiler's scanner by
not modifying filenames in line directives in any form. Specifically,
relative filenames now remain relative. This makes it easier to reason
about the behavior of the scanner but may require clients to adjust
those filenames.
If removing the longer path in the .golden file is not satisfactory,
the (scanner) client may have to massage positions returned via line
directives; or better, the line directives are created with extended
path information.

We used a css-pseudo class rule to move the line number inside
the pseudo element. The idea was to prevent line numbers from getting
selected while copying the code. But this was already implemented
with the "user-select: none" rule.
Since the spec was undefined on "user-select", we had to resort
to the pseudo-class, but now both FF and Chrome implement the correct
behavior.
Hence, moving the content to be inside the span, and removing the
pseudo-class rule.
Manually tested with Chrome 63 and Firefox 58 on Ubuntu.
