084266ed52 fix several problems with config parser: 
a bug where it underflows the string
 a bug where it never frees parser_t struct
make read_config() return 0 if parser is NULL,
 make config_close() accept and ignore NULL parser -
 eliminates many if() blocks
reverse the sense of parser bit flags - negative flags
 are harder to grok.
hexdump: revert the change to use config parser, it is BIGGER
 and also requires additional quirks in parser
*: explicitly use PARSER_NORMAL instead of 0

4795e4e011 Rich Filker spotted that sed -e 's/xxx/[/' didn't work right. Did a smaller 
fix than his, and shrank the code a bit on top of that so the net size is
smaller, and added a test to the test suite for this case.  Plus I cleaned up
the #includes and removed unnecessary "const"s while I was there.

cd82c3c041 Don't do workarounds for broken shells. Busybox is about to grow a shell that 
we can run our own testsuite under, and I want it to handle the full range of
strange and peverted behavior you can find in real world shell scripts.
In the meantime, I'll just say #!/bin/bash in places that may care.

89a22ea5d9 make the testsuite a little less brittle: 
- 'function fn_name\n{' breaks on older FreeBSD default shells, so use the more
  widely supported 'fn_name () {'. This needs more fixing..
- test for integers ought to use the proper operators
- test for strings ought to use quoting of the strings to be fair to strange
  implementations of test(1)
- make sure not to ignore return-codes != 0 from commands; Some shells exit
  immediately on this (much like explicitely requesting set -e in e.g. bash)

TODO:
*) Some older shells do not allow a space after the test-condition in an "if"
statement. This doesn't work:
if [ $status -ne 0 ] ; then
as opposed to this:
if [ $status -ne 0 ]; then
or this
if [ $status -ne 0 ]
then

*) strict spacing between commands. In some shells you have to say:
foo ; bar ; baz
The affected shells barf on stuff like ommitting the space, so this doesn't
work:
foo; bar   ;baz

*) $() vs. ``
The former isn't really portable as opposed to the latter.

*) fix frong assumption that the testsuite is run from the source-dir.
This is a complete misconception and renders the testsuite completely useless.


That said, i note that IMO a test-harness ought to do it's best to work in
a wide variety of environments, everything else defeats it's purpose.

998dbee6d9 Patch from Jean Wolter: 
it looks like the introduced support for character classes and
equivalence classes is not correct. The attached patch tries to fix
some symptoms and tries to make tr behave like gnu tr for the added
test cases. The patch

 - removes if clauses with side effects
 - fixes handling of buffer pointer (strcat added characters to the
   buffer without increasing the buffer pointer)
 - re-arranges character classes to match ASCII order

Jean
