runtime.goidgen can be quite frequently modified and
shares cache line with the following variables,
it leads to false sharing.

This causes the child, if still writing, to get an error or
SIGPIPE and most likely exit so our subsequent wait can
finish.
A more guaranteed fix would be putting a time limit on the
child's overall execution, but this fixes the problem
I was having.

This is the form as returned by Postgres, as well
as JavaScript.
I've tried and failed to find authorative docs online
about the proper string serialization, if any.

Must keep dot and the receiver separate - variables broke that symmetry.
Also clean up function invocation and rename "data" to "dot" for clarity.

Replaces "mkdir -p ..." command, as Windows mkdir command
does not support -p flag. Also, is simpler and faster then
launching new process.

Not strictly necessary (you could achieve the same, clumsily,
via with blocks) but great to have: $x.Field, $y.Method.

We can avoid the check against empty constants (''),
which UnquoteChar doesn't handle well, by leaving on
the trailing quote and seeing that's all we have left at the end.

- suppress the print that -help is not defined.
- return a special error code if -help is set
- do not change behavior if an explict "help" flag is defined.

of the origin.
image/png and image/jpeg benchmarks show no significant changes.
The image/draw changes suggest to me that making a gofix for this is not
feasible. People are just going to have to make manual fixes.

1) Make the value optional ({{template "foo"}})
2) Allow the template identifier to be a thing of type *Template.
The second makes it easy to drop templates in to a set dynamically
during invocation.

It was an ill-advised carryover from the previous template package.
Also clean up function evaluation.
Also add a Name method to Template.
