The link you have above, does reference the use of 'L', but not the derivation.
There is a thread on R-Help from 2012 ("Difference between 10 and 10L"), where Prof. Ripley addresses the issue in response to Bill Dunlap and the OP:
https://stat.ethz.ch/pipermail/r-help/2012-May/311771.html
In searching, I also found the following thread on SO:
https://stackoverflow.com/questions/22191324/clarification-of-l-in-r/22192378
which had a link to the R-Help thread above and others.
