hgdemandimport: use correct hyperlink to python-bug in comments (issue5765) Differential Revision: https://phab.mercurial-scm.org/D1810

monoblue: adjust font size of graph entries /shortlog uses 1.1em font for changesets, so it makes sense to use the same size on /graph too. In practice, 1.2em is 14.784px, and 1.1em is 13.552px.

hgweb: make .info a block element by default Using a <div> instead of a <span> with "display: block" makes more sense. While at it, let's adjust top margin in monoblue so that text in .info doesn't overlap changeset "tags" elements (they are quite large in monoblue).

revlog: don't use slicing to return parents This is the only place we use a slice on index entries, which are currently tuples. In preparation for moving away from tuples, let's stop using slices so we don't have to implement that support on the new type. We also tweak the logic slightly so the exception only catches the IndexError on the index lookup, not on the index entry lookup. The old code should never have been buggy. But it was semantically wrong. Differential Revision: https://phab.mercurial-scm.org/D1764
