Martin Atkins e8dbb16dbc hcl/hclsyntax: Fix up parsing of flush heredocs
This was implemented a long time ago in the original template parser, but
it was missed in the rewrite of the template parser to make it use a
two-stage parsing strategy.

It's implemented as a post-processing step on the result of the first
stage of parsing, which produces a flat sequence of literal strings,
interpolation markers, and control markers, and prior to the second stage
which matches opening and closing control markers to produce an expression
AST.

It's important to do this at parse time rather than eval time since it is
the static layout of the source code that decides the indentation level,
and so an interpolation marker at the start of a line that itself produces
spaces does not affect the result.

HCL Language Test Suite

This directory contains an implementation-agnostic test suite that can be used to verify the correct behavior not only of the HCL implementation in this repository but also of possible other implementations.

The harness for running this suite -- a Go program in this directory -- uses the hcldec program as a level of abstraction to avoid depending directly on the Go implementation. As a result, other HCL implementations must also include a version of hcldec in order to run this spec.

The tests defined in this suite each correspond to a detail of the HCL spec. This suite is separate from and not a substitute for direct unit tests of a given implementation that would presumably also exercise that implementation's own programmatic API.

To run the suite, first build the harness using Go:

go install github.com/hashicorp/hcl2/cmd/hclspecsuite

Then run it, passing it the directory containing the test definitions (the "tests" subdirectory of this directory) and the path to the hcldec executable to use.

For example, if working in the root of this repository and using the hcldec implementation from here:

go install ./cmd/hcldec
hclspecsuite ./specsuite/tests $GOPATH/bin/hcldec

For developers working on the Go implementation of HCL from this repository, please note that this spec suite is run as part of a normal go test ./... execution for this whole repository and so does not need to be run separately.
