[evax]

This adds support for inverted {{^name}}{{/name}} sections.

Thanks @evax, +1.

This PR is a little stale, someone renamed mustache to rebar_mustache. Can we get an update?

[evax]

Will do (@Tuncer paved the way it seems, thanks!)

[evax]

@Tuncer: interesting, I can't get upstream mustache tests to pass, apparently due to a rebar issue :)
It looks like although skip-deps is set to true rebar is trying to compile modules in deps/meck/test/ and fails to do so because of a test-only dependency on hamcrest-erlang.

Still waiting for motion on this.

@tsloughter why did you close this?

Hi, this issue was closed in an attempt to do quick basic filtering, with the benediction of rebar project owners. These issues and pull requests are not issues or code we're spitting on, but given the burden of the task and how much code rot may have happened since these were open is unknown from maintainers at this time. All tickets prior to March 2014 were closed and will be reopened on a per-request basis if we see interest from the reporter or contributor, or if some of the issues reported are still valid after the various patches that have made it since they were opened.

This is a fairly brutal first step to help us get a proper understanding of what is still valid or not, but that has been proven efficient in the past. Sorry for the inconvenience, things should go smoother from there on.
