test-fuzz-targets: look for clang-6.0 binary as well Debian sid is still shipped with clang 4.0 by default. This allows me to run the test without replacing the system clang to clang-6.0.

test-fuzz-targets: rebuild executable silently This makes sure the build is not broken.

fuzz: fix "make clean" to pass even if no binaries built yet

fuzz: compile xdiff.cc with -std=c++17 Otherwise the build would fail as follows: In file included from xdiff.cc:13: ./fuzzutil.h:23:10: fatal error: 'third_party/absl/types/optional.h' file not found #include "third_party/absl/types/optional.h"

fuzz: fix use of undeclared function memcpy()

fuzz: fix the default make target

fuzz: expand variables by make Otherwise it wouldn't work unless CC and CXX were exported from the environment.

templater: always map over a wrapped object _checkeditermaps() is no longer necessary as the hgweb issue was resolved.

templater: consistently join() string-like object per character (BC) The old behavior was copied from join() of a lazy generator string, which was unified to the behavior of join() of a byte string by the previous patch. This patch fixes the mappable type to do the same.

templater: always join() over a wrapped object (BC) This is a behavior change in a sense that join() of a byte string is no longer "implementation dependent." Before, if a byte string was backed by a lazy generator, join() would concatenate each chunk with the specified separator, which seems wrong. The new behavior is always join() each byte. TypeError on join() over uniterable is also fixed.
