Vadim Zeitlin 3f66f6a5b3 Remove all lines containing cvs/svn "$Id$" keyword.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.

If nothing else, this will make an eventual transition to Git simpler.

Closes #14487.

///////////////////////////////////////////////////////////////////////////////
// Name: tests/formatconverter/formatconverter.cpp
// Purpose: Test wxFormatConverter
// Author: Mike Wetherell
// Copyright: (c) 2004 Mike Wetherell
// Licence: wxWindows licence
///////////////////////////////////////////////////////////////////////////////
//
// Notes:
//
// The conversions wxFormatConverter currently does are as follows:
//
// %s, %lS -> %ls
// %S, %hS -> %s
// %c, %lC -> %lc
// %C, %hC -> %c
//
// %hs and %hc stay the same.
//
// %S and %C aren't actually in the ISO C or C++ standards, but they can be
// avoided when writing portable code.
//
// Nor are %hs or %hc in the standards, which means wxWidgets currently doesn't
// have a specifier for 'char' types that is ok for all builds and platforms.
//
// The effect of using %hs/%hc is undefined, though RTLs are quite likely
// to just ignore the 'h', so maybe it works as required even though it's
// not legal.
//
// I've put in some checks, such as this which will flag up any platforms
// where this is not the case:
//
// CPPUNIT_ASSERT(wxString::Format(wxT("%hs"), "test") == wxT("test"));
//
// For compilers that support precompilation, includes "wx/wx.h".
#include "testprec.h"
#ifdef __BORLANDC__
#pragma hdrstop
#endif
// for all others, include the necessary headers
#ifndef WX_PRECOMP
#include "wx/wx.h"
#endif

using std::string;
///////////////////////////////////////////////////////////////////////////////
// The test case
//
// wxFormatConverter only changes %s, %c, %S and %C, all others are treated
// equally, therefore it is enough to choose just one other for testing, %d
// will do.
