Thanks, Alec, that is what I am doing except that I just use the short hash (“e9b577d3”) rather than the 40-character full hash. If I should be using the full hash, I can do that.
AIUI, this causes GitHub to deliver a compressed tarball of a snapshot of the project as of that commit. GitHub creates these tarballs and caches them for some unknown length of time. GitHub _should_ be able to re-create the tarball if the cached version is no longer available since the snapshot should be exactly the same.
My WAG is that the file that differs (‘EXPORTED_VERSION’) is generated by a git hook. It may be that the hook works differently depending on whether the commit hash is the lastest in that branch or not. I know almost nothing about such hooks, however, so I could be entirely wrong.
