Improve large file support
Disable absolute line numbers for large files (currently
anything bigger than 32MiB). This speeds up moving around
with for example nn% since no new lines need to be calculated.
Of course movements like :nn will be unaffected.
The optimizations can be disabled by explicitly enabling
absolute line numbers as in :set number
