Almost all the tr invocations look like converting LF to NUL, except
for two that squash a colon ':', HT and LF all to NUL. Is Solaris's
tr fine with the former but not the latter?

I am not suggesting to keep 'tr "\n" "\0"', but just wanted to make
sure I am reading the first paragraph correctly. If we are
rewriting, we should do so consistently.

What is -pne? Is it the same as -pe?
tr/\n/\0/ (or y/\n/\0/) may be more faithful to the original.

Ditto. We may want to give the same script used in the above two
(and twice again in the later hunk) more descriptive name, e.g.
broken_c_unquote () {
perl -pe '... that script ...' "$@"
}
broken_c_quote stdin >stdin0
Side note: the script is broken as a generic C-unquote function in
multiple ways. It does not work if it has more than one backslash
quoted characters, it does not understand \t, \b, \015, \\, etc. to
name two.
But the breakage does not matter for the strings used in the test
vector.
