Regexp for c-or-c++-mode

[Alan Mackenzie]

Hello, Micha�.

In c-or-c++-mode--regexp, there are several occurrences of

    [ \t\r]

.  These expressions notably lack \n.  This seems strange, given how \n
is the normal line terminator in Emacs and \r is a rarely used artefact.

Is there any reason these expressions are like that, and if so please
tell me that reason.  If there is no such reason, I have a patch ready
to put the \n's into the regexp.

Thanks!
