EOF
cmp -s output - <<EOF
a

The attached patch fixes it.

Patch from Rob Landley;
...
Moving on to building diffutils, busybox sed needs this patch to get
past the first problem. (Passing it a multi-line command line argument
with -e works, but if you don't use -e it doesn't break up the multiple
lines...)

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...)
