When building with the address sanitizer on, free some more resources before
exiting. (This is unnecessary when not looking for memory leaks.)
* src/patch.c (init_files_to_delete): Add dispose function for freeing
filenames.
* src/pch.c (another_hunk): In the (debug & 2) output, fix how empty
lines that are not part of the patch context are printed. Also, add
newlines to lines that are missing them to keep the output readable.

I configured with --enable-gcc-warnings and bleeding-edge gcc
(version 8.0.1 20180406) and hit some warning-escalated-to-errors.
This fixes them:
* src/common.h (FALLTHROUGH): Define.
* src/patch.c (abort_hunk_context): Use FALLTHROUGH macro in place of
a comment. This avoids a warning from -Wimplicit-fallthrough=.
* src/pch.c (do_ed_script): Add otherwise unnecessary initialization
to avoid warning from -Wmaybe-uninitialized.
(another_hunk): Use FALLTHROUGH macro here, too, twice.

* tests/crlf-handling, tests/git-cleanup, tests/test-lib.sh: Use printf
instead of echo -e / echo -n for compatibility with systems that don't
support these echo options.
* tests/merge: Minor other cleanups.
