[format] scriptBuilder parser executes commented out `# %action` statements in YML recipes

[ermo]

In a stone.yml recipe,

# %make

will (quite unexpectedly) get picked up and expanded + run by our macro parser here, essentially making # signs lose their intended meaning as "this is a comment, don't process" in YAML files and shell scripts.

One solution could be to attempt to add findSplitBefore logic, such that the lines the parser sees have already been stripped of comments as it parses them.

Needs a different solution as the "fix" well ... wasn't (it broke builds w/tmpfile macros).
