* bc/utf16-portability-fix (2019-02-11) 1 commit
(merged to 'next' on 2019-02-11 at a33208b3)
+ utf8: handle systems that don't write BOM for UTF-16
* ab/bsd-fixes (2019-02-21) 2 commits
(merged to 'next' on 2019-02-21 at 28d0017056)
+ commit-graph tests: fix cryptic unportable "dd" invocation
+ tests: fix unportable "\?" and "\+" regex syntax
The code and tests assume that the system supplied iconv() would
always use BOM in its output when asked to encode to UTF-16 (or
UTF-32), but apparently some implementations output big-endian
without BOM. A compile-time knob has been added to help such
systems (e.g. NonStop) to add BOM to the output to increase
portability.
Test portability fix.

A new target "coverage-prove" to run the coverage test under
"prove" has been added.
Test portability fix.

+ Revert "t5562: replace /dev/zero with a pipe from generate_zero_bytes"
(this branch is tangled with mk/t5562-no-input-to-too-large-an-input-test.)
Update to the fuzzer.
Part 3 of the test update, to rewrite "generate stream of NULs" in C.
* js/mingw-host-cpu (2019-02-07) 1 commit

(this branch is tangled with js/test-tool-gen-nuls.)
For "rebase -i --reschedule-failed-exec", we do not want the "-y"
shortcut after all.
Part 2 of the fix to t5562 regression, to avoid feeding
http-backend from a pipe.

"git checkout [<tree-ish>] <pathspec>" started reporting the number

+ remote-curl: refactor reading into rpc_state's buf
+ remote-curl: reduce scope of rpc_state.result
+ remote-curl: reduce scope of rpc_state.stdin_preamble
+ remote-curl: reduce scope of rpc_state.argv
Unify RPC code for smart http in protocol v0/v1 and v2, which fixes
a bug in the latter (lack of authentication retry) and generally
improves the code base.
