/// This came about more or less by a complete historical accident,
/// when the original `ls` tried to hide `.` and `..`:
/// https://plus.google.com/+RobPikeTheHuman/posts/R58WgWwN9jp
///
/// When one typed ls, however, these files appeared, so either Ken or
/// Dennis added a simple test to the program. It was in assembler then,
/// but the code in question was equivalent to something like this:
/// if (name[0] == '.') continue;
/// This statement was a little shorter than what it should have been,
/// which is:
/// if (strcmp(name, ".") == 0 || strcmp(name, "..") == 0) continue;
/// but hey, it was easy.
///
/// Two things resulted.
///
/// First, a bad precedent was set. A lot of other lazy programmers
/// introduced bugs by making the same simplification. Actual files
/// beginning with periods are often skipped when they should be counted.
///
/// Second, and much worse, the idea of a "hidden" or "dot" file was
/// created. As a consequence, more lazy programmers started dropping
/// files into everyone's home directory. I don't have all that much
/// stuff installed on the machine I'm using to type this, but my home
/// directory has about a hundred dot files and I don't even know what
/// most of them are or whether they're still needed. Every file name
/// evaluation that goes through my home directory is slowed down by
/// this accumulated sludge.
