/**
 * Removes the indentation shared by every line of a JSX block's children. Only
 * the common part goes, so the structure inside the block is preserved.
 *
 * Lines already claimed by an edit collected inside this block are ignored:
 * their source is either replaced by generated Markdown or dropped, so their
 * indentation says nothing about the text that will remain.
