Fix formatting issues with the documentation added to the new gitformat-* namespace in c0f6dd49f19 (Merge branch 'ab/tech-docs-to-help', 2022-08-14). As this documentation didn't have a wide audience before that, some of these formatting issues pre-dated that change. See [1] for details. But the end result of having some paragraphs use "<p>" in the HTML output, and to have others wrapped in "<pre><code>" doesn't look nice. The most minimal way to fix this is to de-indent the opening line of paragraphs that don't start with another formatting element (e.g. "*" or "-" would already format them as text). Let's do that. 1. https://lore.kernel.org/git/221109.86bkpgriso.gmgdl@evledraar.gmail.com/ Reported-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> --- There's a lot more to fix in these gitformat-* docs (as their formatting was funny before), but this is a minimal change to fix the most major issues.
