Hi all,

I have an urgent showstopper on all my documents:

if one uses source blocks with linenumbers enabled and more than 9 (>= 10) lines inside the block, I get an error.
This small adoc preproduces the error (see below):

= Test
:lang: de
:numbered:
:source-highlighter: pygments
:pygments-css: class

[source,java,linenums,indent=0]

The call:

~/.gem/ruby/2.6.0/gems/asciidoctor-pdf-1.5.0.beta.2/bin/asciidoctor-pdf  --trace  -o test.pdf test.adoc

The error is:
