* util.c, include/ruby/util.h (ruby_add_suffix): remove the function.
[Bug #5153] [ruby-core:38736] * io.c (argf_next_argv): remove the call of above function. * ext/-test-/add_suffix, test/-ext-/test_add_suffix.rb: remove the test extension module because this is only for testsing ruby_add_suffix(). * LEGAL: remove the mention about a part of util.c, because now we removed the part. * io.c (argf_next_argv): now the new filename is not guranteed to use, so should check the return value of rename(2). * test/ruby/test_argf.rb (TestArgf#test_inplace_rename_impossible): now we expect same result with other platforms on no_safe_rename platforms (=Windows). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@32826 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

- * Suffix appending for in-place editing under MS-DOS and OS/2 (and now NT!).
- *
- * Here are the rules:
- *
- * Style 0: Append the suffix exactly as standard perl would do it.
- * If the filesystem groks it, use it. (HPFS will always
- * grok it. So will NTFS. FAT will rarely accept it.)
- *
- * Style 1: The suffix begins with a '.'. The extension is replaced.
- * If the name matches the original name, use the fallback method.
- *
- * Style 2: The suffix is a single character, not a '.'. Try to add the
- * suffix to the following places, using the first one that works.
- * [1] Append to extension.
- * [2] Append to filename,
- * [3] Replace end of extension,
- * [4] Replace end of filename.
- * If the name matches the original name, use the fallback method.
- *
- * Style 3: Any other case: Ignore the suffix completely and use the
- * fallback method.
- *
- * Fallback method: Change the extension to ".$$$". If that matches the
- * original name, then change the extension to ".~~~".
- *
- * If filename is more than 1000 characters long, we die a horrible
- * death. Sorry.
- *
- * The filename restriction is a cheat so that we can use buf[] to store
- * assorted temporary goo.
- *
- * Examples, assuming style 0 failed.
- *
- * suffix = ".bak" (style 1)
- * foo.bar => foo.bak
- * foo.bak => foo.$$$ (fallback)
- * makefile => makefile.bak
- * suffix = ".$$$" (style 1)
- * foo.$$$ => foo.~~~ (fallback)
- *
- * suffix = "~" (style 2)
- * foo.c => foo.c~
- * foo.c~ => foo.c~~
- * foo.c~~ => foo~.c~~
- * foo~.c~~ => foo~~.c~~
- * foo~~~~~.c~~ => foo~~~~~.$$$ (fallback)
- *
- * foo.pas => foo~.pas
- * makefile => makefile.~
- * longname.fil => longname.fi~
- * longname.fi~ => longnam~.fi~
- * longnam~.fi~ => longnam~.$$$
- *
