The file lexor.lex was beginning to suffer a catastrophic increase in entropy due mainly to the mingling of spaces and tabs--an age-old problem that often finds itself as the subject of many a religious war. The key rule: Make it consistent in as many editors as possible; this was achieved by converting all hard tabs into soft tabs (composed of spaces) of width 4. I couldn't help but make modifications to the code as I tabifified, but most of the changes are strictly style. While maintainers generally treat large scale whitespace and formatting changes with much caution, I believe that the code is now much more maintainable; moreover, the test suite produces the same results as before.
