Muse reader: paragraph indentation does not indicate nested quote
Muse allows indentation to indicate quotation or alignment,
but only on the top level, not within a <quote> or list.
This patch also simplifies the code by removing museInQuote
and museInList fields from the state structure.
Headers and indented paragraphs are attempted to be parsed
only at the topmost level, instead of aborting parsing with guards.
