1.7 bug; 2.0.0 beta 2

The 2.0.0 beta 2 is out. LEnts have been reworked--they are no longer Topics.

• Use lents to set up a LSec for LEnts, then
• Use ch to add/change/remove LEnts from the text content of that LSec.

LEnts should now be very much faster to work with. And yes, if you include several LSecs, then the le command can display the consolidated set of LEnts.

Meanwhile, I'm starting to get a handle on that bug in 1.7 that I reported in the CompStrm forum.
