graph: in hgrc specify line color for main branch
You can specify color to visually distinguish main branch (trunk)
on hgweb's graph page. If color specified, all branch heads will share
same color. Settings format is branch_name.color = value, where color
is six hexadecimal digits e.g.:
[graph]
default.color = FF0000
