I will.. guess I worked too long and got too familiar with
that, so it did not occur to me there's explanation needed ;-)

the idea is to move to generic annotation_line struct in generic places
so it can work over different sources

both browser_disasm_line and disasm_line__browser lost the 'disasm'
by using the generic annotation_line struct.. so there's no need
to keep it in its name

I'll update changelogs and resend/repush
