* maint: add an assertion to suppress clang-detected warningJim Meyering2009-11-201-2/+6
| | | | | | | | The clang static analyzer reported that a NULL parent could be dereferenced. However, that cannot happen, because for all callers, the parameter, parent, is always non-NULL at that point. * src/diff.c: Include <assert.h>. Assert that parent is not NULL.
* maint: remove dead assignment from diff3.cJim Meyering2009-11-201-1/+0
| | | | * src/diff3.c (make_3way_diff): Remove dead assignment.

| | | | | * man/Makefile.am (dist_man1_MANS): Rename from dist_man_MANS, to enable better automake-generated installation rules.

| | | | | | | | * src/Makefile.am (paths.h): Emit a definition of DEFAULT_DIFF_PROGRAM that is simply "diff" (or whatever $(transform) would convert that to, e.g., "gdiff"). This makes it so that tests can work without first installing diff, and so that the binaries do not hard-code $(prefix). * NEWS (Changes in behavior): Mention this.
* tests: add the first script; hook up gnulib-testsJim Meyering2009-11-147-4/+686
