tags: rename "head" to "node" where we don't care
Followup to
5eb4d206202b (tags: extract fnode retrieval into its own
function, 2017-03-28) in which the "for head in head" became "for head
in nodes".
manifest: update comment to be about bytearray
Looks like a leftover from
2a18e9e6ca43 (py3: use bytearray() instead
of array('c', ...) constructions, 2017-03-12).
hgweb: rename linerangelog.js as followlines.js
So that the file name matches both the feature name and user facing vocabulary
(e.g. the revset function).
hgweb: rely on a specific class to change cursor type in followlines UI
The previous CSS rule would also apply in pages where followlines UI was not
available (e.g. "changeset" view at /rev/<node>/). We insert a
"followlines-select" class in JavaScript on actually selectable lines and
restrict the CSS selector to use it.
