[PATCH] Command line parsing of ls, tail and wc with genparse

[Michael Geng]

Hi Eric, Jim, hello mailing list,

I again generated a patch to the Coreutils which calls genparse
for generating command line parsers for the ls, tail and wc 
commands. Some differences to the last patch I submitted:

1. It now passes "make distcheck".

2. It is targeted to the CVS version of the Coreutils from Sept 04. 
   It applies also to today's version without conflicts but I have
   problems to build it since Sept 10.

3. A new directive __NEW_PRINT__ allows partitioning of text in
   the usage function. This way it finds the existing translations.

4. The genparse (.gp) file can now include other genparse files
   using the #gp_include directive. So it is now possible to extract
   common command line switches like --help and --version to a
   seperate file which can be included by the other genparse files.

5. A new __COMMAND__ directive allows the instantiation of functions
   in the usage () function. This allows to keep the 
   emit_bug_reporting_address () function which was recently 
   introduced.

6. It is possible to let genparse break lines to a specified width
   automatically as you suggested, Eric. That's a smart extension
   to genparse but I wouldn't propose to use it for the Coreutils
   because manual formatting of the help text in order keep 
   compatibility to the existing translations appears to be the
   more important goal.

7. The generated code (and the genparse source code) insert a
   space before opening braces '(' according to the GNU coding style.
   Please let me know if you find more non conformances.

Michael
