In the intended usecase where this serves as a hack there is no problem
with double/single quotes being present as we write it to a log file
only, but nowadays our calling of apt-key produces a temporary config
file containing this "setting" as well and suddently quoting is
important as the config file syntax is allergic to it.
So the fix is to ignore all quoting whatsoever in the input and just
quote (with singles) the option values with spaces. That gives us 99% of
the time the correct result and the 1% where the quote is an integral
element of the option … doesn't exist – or has bigger problems than a
log file not containing the quote. Same goes for newlines in values.

space-gapping: '-o option= value'
That is a very old feature (straight from 1998), but it is super
surprising if you try setting empty values and instead get error
messages or a non-empty value as the next parameter is treated as the
value – which could have been empty, so if for some reason you need a
compatible way of setting an empty value try: '-o option="" ""'.
I can only guess that the idea was to support '-o option value', but we
survived 17 years without it, we will do fine in the future I guess.
Similar is the case for '-t= testing' even through '-t testing' existed
before and the code even tried to detect mistakes like '-t= -b' … all
gone now.
Technically that is as its removing a feature replacing it with another
a major interface break. In practice I really hope for my and their
sanity that nobody was using this; but if for some reaon you do: Remove
the space and be done.
I found the patch and the bugreport actually only after the fact, but
its reassuring that others are puzzled by this as well and hence a
thanks is in perfect order here as the patch is practical identical
[expect that this one here adds tests and other bonus items].
Thanks: Daniel Hartwig for initial patch.

The general idea is: A small paragraph on the tool itself as a
description, a list of the most used (!= all) commands available in the
tool, a remark where to find more information on the tool and its
commands (aka: in the manpage) and finally a common block referring to
even more manpages. In exchange options are completely omitted from the
output as well as deprecated or obscure commands. (Better) Information
about them is available in the manpages anyway and the few options which
were listed before were also the least interesting ones (-o -c -q and co
are hardly of interest for someone totally new looking to find info by
asking for help and anyone with a bit of experience doesn't need this
short list. Those would need a list of options applying to the command
they call, but they are too numerous and command specific to list them
sanely in this context.

Its not as simple as I initially thought to abstract this enough to make
it globally usable, so lets not pollute global namespace with this for
now.

This ensures that location strings loaded from a location specified via
configuration (Dir::Locale) effect the help messages for commands.

This used to work before we implemented a stricter commandline parser
and e.g. the dd-schroot-cmd command constructs commandlines like this.

StringToBool uses strtol() internally to check if the argument is
a number. This function stops when it does not find any more numbers.
So a string like "0ad" (which is a valid packagename) is interpreted
as a "0". The code now checks that the entire string is consumed
not just a part of it. Thanks to Johannes Schauer for raising this
issue.

My commit 45df0ad2 from 26. Nov 2009 had a little remark:
"The commit also includes a very very simple testapp."
This was never intended to be permanent, but as usually…
The commit adds the needed make magic to compile gtest statically
as it is required and links it against a small runner. All previous
testcase binaries are reimplemented in gtest and combined in this
runner. While most code is a 1:1 translation some had to be rewritten
like compareversion_test.cc, but the coverage remains the same.

Beside being a bit cleaner it hopefully also resolves oddball problems
I have with high levels of parallel jobs.
