[AC21.5] sync to etags_pot_version 17.19

APPROVE COMMIT 21.5 Vin, I can submit a patch for 21.4 too if you like. It's 219KB, though, and ISTR there was some concern about syncing to Francesco's version being right for 21.4, so I'll wait for an invitation. (I still owe you the patch for the metacity maximize bug, don't I .... Tomorrow.) This patch is in response to the report by Morgon Kanter <morgon(a)surgo.net&gt; that the man page was out of sync with reality. Since Francesco released a new version recently, I synced etags.1 to that, and since I was doing that much, etags.c, too. Almost all of the changes to etags.c involve removal of feature macros that are never used in practice any more. There are a couple of small changes, recognition of new keywords, mostly. So I think this is "safe".
