browsercolumn: Fix relative line number width

For relative line numbers the width that actually matters is the width
for all the displayed line numbers. The width of the largest index of
the displayed files doesn't matter. Only the width of the relative
indices and the width of the currently highlighted item's index, unless
`relative_current_zero` is enabled.
