Add globbing pattern support to #include and #include_once
* doc/grecs-syntax.texi: Document changes to the #include statement. * doc/grecs_config.5: Likewise. * src/preproc.c (include_glob, include_pos) (include_once): New statics. (pp_list_find): Return 0 if list is NULL. (incl_copy): New statics. (source_lookup): Use incl_copy as the copy function. (pop_source): If more glob expansions are available, push next one onto input stack. (isglob): New static. (parse_include): Support globbing patterns. * tests/Makefile.am: Add new testes. * tests/testsuite.at: Likewise. * tests/incl00.at: New test case. * tests/incl01.at: New test case. * tests/incl02.at: New test case. * tests/incl03.at: New test case.
