This was done by Romain Tartière for PR123553. I initially thought that it would break code like this:
#define b00101010 -1
if (0 b00101010)
...
by joining 0 and b00101010 together. However, the real problem with that patch was that once it saw a 0, it assumed that the number was base 2, 8 or 16, ignoring base 10 floating point numbers. I fixed that.
I didn't copy the diagnostic part of the original patch as it seems out of scope of implementing binary integer literals formatting.

test suite
This change does the following:
- Introduces symmetry in the test inputs/outputs by adding the exit
code to the files. This simplified the test driver notably by
requiring less filename/test name manipulation.
- Adds a test driver for the testcases added in r313544, patterned
after bin/sh/tests/functional_test.sh . The driver calls indent as
noted in r313544, with an exception: The $FreeBSD$ RCS keyword's
expansion is reindented with indent, which means that the output
differs from the expected output. Thus, all lines with $FreeBSD$
in them are deleted on the fly, both in the input file and the
output file.
The test inputs/outputs are copied to the kyua sandbox before the
test is run as the pathing in some of the files relies on pathing
normalized to the current directory (copying the files is the
easiest way to resolve the issue).

These examples show expected behavior of indent(1). They are meant to be used
together with a regression test mechanism, either Kyua, a Makefile or perhaps
something else. The mechanism should in essence do this:
indent -P${test}.pro < ${test}.0 > ${test}.0.run
and compare ${test}.0.stdout to ${test}.0.run. If the files differ or the exit
status isn't 0, the test failed.
* ${test}.pro is an indent(1) profile: a list of options passed through a file.
The program doesn't complain if the file doesn't exist.
* ${test}.0 is a C source file which acts as input for indent(1). It doesn't
have to have any particular formatting, since it's the output that matters.
* ${test}.0.stdout contains expected output. It doesn't have to be formatted in
Kernel Normal Form as the point of the tests is to check for regressions in
the program and not to check that it always produces KNF.
