* generic/tclBasic.c: Fix for (among others) [Bug 2699087]
* generic/tclCmdAH.c: Tailcalls now perform properly even from
* generic/tclExecute.c: within [eval]ed scripts.
* generic/tclInt.h: More tests missing, as well as proper
exploration and testing of the interaction with "redirectors" like
interp-alias (suspect that it does not happen in constant space)
and pure-eval commands.
