Nice work, indeed.

Additionally to Eric's comment, I'd suggest to increase the coverage
for 'echo' to about 100% [1] with the attached patch:

*  src/echo.c (usage): Assert that STATUS is always EXIT_SUCCESS.
* tests/misc/echo.sh: Add further tests for all hex and escape and
escape characters.

You may simply squash it in.

[1] To get coverage statistic, run:
  make coverage -j 4 TESTS=tests/misc/echo.sh SUBDIRS=.
  xdg-open file:doc/coverage/src/echo.c.gcov.frameset.html


Have a nice day,
Berny
