+    maint: avoid warnings from GCC8
+    
+    Hi Andreas,
+    
+    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.

+    
+    * src/safe.c (min_cached_fds): Define minimum number of cached dir file

+    RLIM_INFINITY.  Set the initial hash table size to min_cached_fds, independent

+
+    Don't leak temporary file on failed ed-style patch
+    
+    Now that we write ed-style patches to a temporary file before we
+    apply them, we need to ensure that the temporary file is removed
+    before we leave, even on fatal error.
+    
+    * src/pch.c (do_ed_script): Use global TMPEDNAME instead of local
+      tmpname. Don't unlink the file directly, instead tag it for removal
+      at exit time.
+    * src/patch.c (cleanup): Unlink TMPEDNAME at exit.
+    
+    This closes bug #53820:
+    https://savannah.gnu.org/bugs/index.php?53820
+

+
+    Don't leak temporary file on failed multi-file ed-style patch
+    
+    The previous fix worked fine with single-file ed-style patches, but
+    would still leak temporary files in the case of multi-file ed-style
+    patch. Fix that case as well, and extend the test case to check for

+    
+    * src/pch.c (another_hunk): In the (debug & 2) output, fix how empty

+    newlines to lines that are missing them to keep the output readable.
