[PATCH v6 0/7] line range highlight

Fri Jun 29 03:39:54 CEST 2018

The following series adds the ability to direct the browser
to highlight specific lines and ranges of lines in
/tree/, /source/, and /blame/ views, using the existing
#URLs.

As part of the implementation it adds a new cgit.js file
that is included in cgit page <head> along with a new
config "js" to specify its url, defaulting to "/cgit.js".
It can be disabled by setting the "js" config to an empty
string.

Highlit lines or ranges are centred vertically rather than
the default of scrolled to the top of the browser window
area.

You can click on the line number links to highlight
individual lines, or line ranges when an individual line
is already highlit.  If a range is highlit, clicking on
a line number link clears the range and just highlights
that line again.

When you click on a line number link, a sticky "burger" menu
(***) appears on the left of the link.  If you click on
this, a popup menu appears with the options

Copy Lines
Copy Link
View / Remove Blame (which depends if you are in /blame/)

Copy Lines copies the text in the line or range that is highlit
into the clipboard.  Copy Link copies the full #URL from the
browser URL bar.  View / Remove Blame toggles between /tree/
and /blame/ views at the same highlit range.

CSS transitions are used throughout.

v6 switches to the burger menu and introduces the popup menu
and related option.  There's some cleanup of the JS and
introduce a copyright notice at the top.
