Update regex ref. logs

Bruno had altered the test, but I'd missed that: still need engine-dependent files as there are
other places that things vary.

Alter another test to avoid long lines

This one is trickier: instead of converting all bytes from 0 to 255 in one go
and displaying this in the terminal, we now test each chunk of 16 consecutive
bytes separately.  This makes for shorter lines and no need for a LuaTeX log.

Catch erroneous regex input (trailing \cL) (fixes #140)

I am working on a test file to probe various erroneous inputs
for l3regex, but there are a couple bugs in other parts that
I need to fix before the test file works.
