hgweb: show each obsfateentry on its own line Commits with more than one reason for being obsolete used to just show obsfate entries all on one line, and that doesn't look good. Let's show each entry on its own line. In paper and coal the lines are simply split using a <br> element, and in other hgweb themes each entry has its own table header. This is done by analogy with changeset parents and children -- in paper and coal they are all put into one table row, and everywhere else each one gets a separate row.
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
