[PATCH 1/3] Modify tr expressions so that xpg4/tr handles it on Solaris

[Ben Walton]

It seems that xpg4/tr mishandles some strings involving [ not followed
by a character class:
% echo '[::1]' | /usr/xpg4/bin/tr -d '[]'
[::1

% echo '[::1]' | /usr/xpg4/bin/tr -d '['
usr/xpg4/bin/tr: Bad string.

This was breaking two tests. To fix the issue, use the octal
representations of [ and ] instead. Reference the octal expression as
a newly exported variable so that it's shared across tests and more
easily understood when reading it.

[PATCH 2/3] Fix sed usage in tests to work around broken xpg4/sed on Solaris

[Ben Walton]

The space following the last / in a sed command caused Solaris'
xpg4/sed to fail, claiming the program was garbled and exit with
status 2:

% echo 'foo' | /usr/xpg4/bin/sed -e 's/foo/bar/ '
sed: command garbled: s/foo/bar/
% echo $?
2

Fix this by simply removing the unnecessary space.

[PATCH 3/3] Fix sed usage in tests to work around broken xpg4/sed on Solaris

[Ben Walton]

In 99094a7a, a trivial && breakage was fixed. This exposed a problem
with the test when run on Solaris with xpg4/sed that had gone silently
undetected since its introduction in e4bd10b2. Solaris' sed executes
the requested substitution but prints a warning about the missing
newline at the end of the file and exits with status 2.

% echo "CHANGE_ME" | \
tr -d "\\012" | /usr/xpg4/bin/sed -e 's/CHANGE_ME/change_me/'
sed: Missing newline at end of file standard input.
change_me
% echo $?
2

To work around this, use perl to perform the substitution instead.

Did you mean '-lpe' or better '-pe' here?

While it's true that the reader may be able to consult the commit
message to learn more about "squarebrackets" and "tr", this might be
one of those cases where either a more explanatory in-code comment is
warranted or the comment should be dropped altogether, since the the
current comment is not illuminating. I'd vote for expanding the
comment a bit to mention "some versions of Solaris 'tr'" and a short
description of the misbehavior.

Also, Hannes wondered how Solaris 'tr' would react to '[][]'. Were you
able to test that or the alternative '[[]]'?
