* generic/tclEnv.c (ReplaceString): Clear memory correctly when
growing the cache to avoid reads of uninitialised data.
* generic/tclStrToD.c (AccumulateDecimalDigit): Fixed a mistake
where we'd run beyond the end of the 'pow10_wide' array if
a number begins with a string of more than 'maxpow10_wide' zeroes.
Both these issues reported under [Bug 1705778] - detected with
the existing test suite, no new regression tests required.
