The *Encoder is almost always garbage. It doesn't need an
encodeState inside of it (and its bytes.Buffer), since it's
only needed locally inside of Encode.

cmp(1) on FreeBSD requires two file arguments.  grep -P on Linux (at least
Ubuntu 12.04) is described in the man page as "This is highly
experimental" and doesn't seem to work. On FreeBSD the man page states
"This option  is not supported in FreeBSD."  Needed this to work while
debugging some funky behavior of 'Import' in my local vim setup.

Slightly modified version of dvyukov's CL 9259045.

No test yet.  Before this CL, the test described in issue 5422
would fail about every 40 times for me.  With this CL, I ran
the test 5900 times with no failures.

Allows Examples with KeyValue expressions to be playable in godoc.

During the traversal of the abstract syntax tree any KeyValueExpr Key.Name was incorrectly being added as an unresolved identifier.
Since this identifier could not be provided the Example was marked as unplayable.
This updates the AST traversal to skip Keys (but continue traversing the Values).

Example of problematic AST now fixed (see L99 where "UpperBound" was being added as a missing identifier):
