etags for C++

[Tak Ota]

I always forget the find command syntax to create TAGS file and refer
to info page for etags.  Following is the example in the info page
that I rely on.  Many times, I struggle to incorporate C++ files.

     find . -name "*.[chCH]" -print | etags -

I suppose use of C++ is very common these days.  Can we modernize this
part of the document like this?

  by typing a dash in place of the file names, like this:
  
  @smallexample
! find . -name "*.[chCH]" -print | etags -
  @end smallexample
  
    Use the option @address@hidden to specify the language

  @smallexample
! find . -iregex '.*\.\(c\|h\|cpp\|cc\)' -print | etags -
  @end smallexample
  
    Use the option @address@hidden to specify the language


Or, is it worth introducing a new command in etags.el that runs find
and etags?
