Usage of SyntaxHighlight_GeSHi language modules follows a classic 80-20 pattern, with the top 20 languages accounting for 81.78% of usage. We could dramatically reduce the footprint of SyntaxHighlight_GeSHi by taking this into account.
The following statistics are based on two hours' worth of requests, collected on cp1056 (bits eqiad) via varnishncsa:
```
varnishncsa geshi_usage -F "%q" -m RxURL:ext.geshi.language 2>&1 | grep --line-buffered -Po '(?<=ext.geshi.language.)\w+' > geshi.log
```
* The top 5 languages account for 45% of usage.
* The top 10 languages account for 65.28% of usage.
* The top 50 languages account for 94.50% of usage.
* The top 100 languages account for 99.45% of usage.
* The top 125 languages account for 99.83 of usage
* The top 142 languages account for 100% of usage.
GeSHi supports 215 languages. I would like to drop support for the 73 languages that were not seen in the logs. The remaining 142 languages should be be grouped strategically.
