Tangentially related:
I cannot find the information about the importance of the - symbol preceding the license block.
Is it used to find the license block when auditing licensing information or something similar?

Once, long ago, indent(3) would not touch comments starting with /*-. But not too many people used it. Fast forward to the 90s or early 2000s. I wrote a crappy tool to parse out license statements. It was super ugly perl and super slow. So I repurposed that as a marker, convinced the project to adopt it and touched almost every file in the tree. The parser was faster, but I couldn't get it released. I think nobody else ever used it.

So, it's officially part our guides. But it could be dropped in new stuff..

Wonderful info! My main issue with it was adapting it to other languages, more specifically, lua (---?), I've seen it in some shell scripts (and atf-sh scripts) as well (#-). Knowing where it came from and that it can be omitted is good to know, thank you!
