pgindent excluded files list

I propose that we create a file containing the list of patterns to 
exclude from pgindent runs. It would look like this:
   #list of file patterns to exclude from pg_indent runs   /s_lock\.h$   /ecpg/test/expected/   /snowball/libstemmer/
/ecpg/include/(sqlda|sqltypes)\.h$  /ecpg/include/preproc/struct\.h$   /pl/plperl/ppport\.h$
 


Then a pgindent run would look like this:
   find . -name '*.[ch]' -type f -print | \   egrep -v -f src/tools/pgindent/exclude_files | \   xargs -n100 pgindent
src/tools/pgindent/typedefs.list    
 

which is shorter and more efficient and less error prone than the way it's done in the current instructions (which puts
thepatterns to be excluded in a series of egrep pipes).
 

Thoughts?

cheers
