* doc/tclvars.n:

* generic/tclStrToD.c:
* generic/tclUtil.c (Tcl_PrintDouble):
* tests/util.test (util-16.*): Restored full Tcl 8.4 compatibility
for the formatting of floating point numbers when $::tcl_precision
is not zero. Added compatibility tests to make sure that excess
trailing zeroes are suppressed for all eight major code paths.
