I think you will not find another place with a '_' as suffix to a parameter. What is the semantic for that? (I assume you use it in other projects?)


Line 363: 	const char *description = counter->description ? counter->description : "";
Have you encountered counters without a description?


Line 397: 		description,
For XML there is something like xml_escape. Do we need (and can we) escape characters for asciidoc? E.g. if the description includes '|'?

No idea what's the semantic, but I did it similiar to http://git.osmocom.org/libosmocore/tree/src/stats.c#n479


Line 363: 	const char *description = counter->description ? counter->description : "";
> Have you encountered counters without a description?
yes. `struct osmo_counter` doesn't have one.

we can escape those by backslashes. Do we need this to do it right now? http://www.methods.co.nz/asciidoc/faq.html#_how_can_i_escape_asciidoc_markup

What do you think? I think we should escape what needs to be escaped? I mean we do it for XML and it should be easy to copy that code?

I agree with holger, we should escape it, to prevent any strange future failures.
