Another common gotcha (at least it is a frequently-reported non-bug):
When using sort on a particular field, you almost always want '-k1,1',
not '-k1'. While sorting from field 1 to the end of the line sometimes
works (particularly for -n), it is a trap for the novice who doesn't
realize that -k1,1 is more precise, where the trailing delimiter and
subsequent fields can't affect the results.
