doc: Don't indent main text in PDF output
Code listings exceed the paper width, leading to results like this:
I consider it completely useless that the PDF output has such a ridiculously large indentation of the main text, taking away precious horizontal space urgently needed for verbatim data.
Ideally, FontConfig should come with a stylesheet for the SGML-to-PDF conversion, taking care of the following issues.
- Handle tabs in code listings to avoid problems like #343 (closed).
- Don't indent the main text; there are already large section titles.
- Reduce the remaining indentation levels to appropriate values for printed output. Right now, they simply reflect
nroff
output, which looks bad.
