pub const SH_GEN_START: &str = "# --- generated: choir surface, do not edit ---";Expand description
The same pair for a shell file, where an HTML comment is a syntax error rather than a comment.
Learned by running sh -n on the first generated copy: the markers
spliced in cleanly, the file was well-formed markdown, and sh
refused it at line 120. A generated artifact nobody executes is one
nobody notices is broken.
