Some locales even have multi-character exponent separators. Scan the actual locale-appropriate separator to determine whether it contains any cased characters; if upper, prefer 'E' format, of lower prefer 'e'; but match the case of the input string in any case, when it has case. Use 'e' when it has no case. This doesn't currently change any test data, due to the bug that QLocale::toString(double, 'e',...) uses the locale-appropriate case, even if that is upper-case, contrary to its own docs. However, fixing that bug breaks some of the tests of QDoubleValidator without this fix to prepare for it.
