d3612178b7 Patch by Junio C Hamano to workaround a gcc compiler bug.
The construct certain vintages of GCC (the one I have trouble
with is 3.2.3) have trouble with looks like the following:

    static struct st a;
    static struct st *p = &a;
    struct st { int foo; };
    static void init(void) { a.foo = 0; }

The problem disappears if we move the struct declaration up to
let the compiler know the shape of the struct before the first
definition uses it, like this:

    struct st { int foo; }; /* this has been moved up */
    static struct st a;
    static struct st *p = &a;
    static void init(void) { a.foo = 0; }

a3822de23e Patch from Bastian Blank to fix a problem when runing find under ash.
"If the shell is compiled with -DJOBS, this is all fine -- find wasn't
stopped (it was killed), so it correctly uses WTERMSIG instead of WSTOPSIG.
However, if the shell _isn't_ compiled with -DJOBS (which it isn't in d-i),
only WSTOPSIG is used, which extracts the high byte instead of the low
byte from the status code.  Since the status code is 13 (SIGPIPE), "st"
suddenly gets the value 0, which is equivalent to SIGEXIT. Thus, ash prints
out "EXIT" on find's exit."

47e5ca1ecb Patch by Jean Wolter to fix a bug where a script wouldnt be executed
unless it had #!/bin/sh in the first line

"It correctly locates the script, tries to execute it via execve which
fails. After that it tries to hand it over to /bin/sh which fails too,
since ash

    - neither provides the absolute pathname to /bin/sh
    - nor tries to lookup the script via PATH if called as "sh script"
"

edc388cf4e The previous fix for 's/a/1/;s/b/2/;t one;p;:one;p' broke the case of
echo fooba | ./busybox sed -n 's/foo//;s/bar/found/p'

I really need to start adding these tests to the testsuite.

8aac05bfe5 Patch from Rob Landley
Fixed a memory leak in add_cmd/add_cmd_str by moving the allocation
of sed_cmd down to where it's actually first needed.
                                                                                
In get_address, if index_of_next_unescaped_regexp_delim ever failed, we
wouldn't notice because the return value was added to idx, which was 
already guaranteed to be > 0.  (This is buried in the changes made when 
I redid get_address to be based on pointer arithmetic, because all the tests 
were gratuitously dereferencing with a constant zero, which wasn't obvious.)
         
Comment in parse_regex_delim was wrong: 's' and 'y' both call it.
 
The reason "sed_cmd->num_backrefs = 0;" isn't needed is that sed_cmd was
allocated with cmalloc, which zeroes memory.

Different handling of space after \ in i...

Different handling of pattern "s/a/b s/c/d"

Cool, resursive reads don't cause a crash. :)

Fixed "sed -f blah filename - < filename" since GNU sed was handling 
both - and filenames on the same line.  (You can even list - more than 
once, although it's immediate EOF...)
