Last change on this file since 33862 was 33862, checked in by vboxsync, 14 years ago

iprt/cpp/ministring.h: Changed the substring constructors to match std::string. As I feared, this caused some minor issues with the format+va_list constructor, fortunately it's only when passing a_cchSrc=0. While at it, I've added the one missing std::string constructor, the repeat character constructor.
