[Bug: 21.4.19] triple slash comment confuses c-show-syntactic-information

================================================================ Dear Bug Team! It appears that cc-mode running in xemacs gets confused by triple slashes. Here's how you should be able to repeat the problem I'm seeing 1) Start up xemacs. (I'm running in Windows XP by double clicking the icon.) 2) Create a new file "MyNewFile.cpp" The way I created it was C-x C-f NewFile.cpp <ret> At this point the mode line says C++ 3) Type the following into the NewFile.cpp buffer class Foo { /// /// Just foo it /// 4) Move the cursor to the "Just foo it" line 5) Hit C-c C-s In the mini-buffer XEmacs will print syntactic analysis: ((topmost-intro-cont 18) (comment-intro)) If we had run this test in Emacs it would have printed syntactic analysis: ((inclass 15) (topmost-intro 17) (comment-intro)) For some reason the "///" will make cc-mode in xemacs think we've left the class definition. If I use "//" for the comment instead of "///" then xemacs returns the same result from c-show-syntactic-information as what emacs returns. ================================================================ System Info to help track down your bug: --------------------------------------- OS version: Microsoft Windows XP [Version 5.1.2600] OS: Windows_NT XEmacs 21.4.19 "Constant Variable" configured for `i586-pc-win32'.
