Mercurial > hg
annotate hgext/uncommit.py @ 35018:7790c4243f8f
paper: apply styles from annotate tooltip to followlines popup
These new colors and styles are already used in the tooltip that gets shown
when user hovers over line numbers on annotate page. The old styles, replaced
in this patch, look completely unrelated to paper or any other hgweb theme.
