Previously, when using the rendering in buffers.vim, the tabline only
considered the current buffer and column width when checking for
updates, despite optionally using the tab number in rendering. This
would cause incorrect tabline rendering when switching between tab pages
if the buffer and column width didn't change. This change mimics the
already existent behavior in `tabline/tabs.vim` which caches the current
tab number for comparison when updating. Some other formatting is
changed to align `buffers.vim` to `tabs.vim`.
