[TSVN] PreserveChdir improvement

Hi,

Further to my other notes about performance, the appended version of the
PreserveChdir class destructor reduces my (highly artificial) test run time
from around 500ms to around 350, which seems worthwhile.

Cheers,

Will

PreserveChdir::~PreserveChdir()
{
   TCHAR currentDirectory[MAX_PATH + 1];

   // _tchdir is an expensive function - don't call it unless we really have to
   tgetcwd(currentDirectory, MAX_PATH);
   if(_tcscmp(currentDirectory, originalCurrentDirectory) != 0)
   {
      _tchdir(originalCurrentDirectory);
   }
}
