f15dfd86c4 ed: don't use memcpy with overlapping memory regions
The memcpy invocations in the subCommand function, modified by this
commit, previously used memcpy with overlapping memory regions. This is
undefined behavior. On Alpine Linux, it causes BusyBox ed to crash since
we compile BusyBox with -D_FORTIFY_SOURCE=2 and our fortify-headers
implementation catches this source of undefined behavior [0]. The issue
can only be triggered if the replacement string is the same size or
shorter than the old string.

Looking at the code, it seems to me that a memmove(3) is what was
actually intended here, this commit modifies the code accordingly.

5a9d2b6e02 libbb: make '--help' handling more consistent
Running an applet with '--help' as its only argument is treated
as a special case.  If additional arguments follow '--help' the
behaviour is inconsistent:

- applets which call single_argv() print help and do nothing else;

- applets which call getopt() report "unrecognized option '--help'"
  and print help anyway;

- expr says "expr: syntax error" and doesn't print help;

- printenv silently ignores '--help', prints any other variables
  and doesn't print help;

- realpath says "--help: No such file or directory", prints the path
  of any other files and doesn't print help.

If the first argument is '--help' ignore any other arguments and print
help.  This is more consistent and most likely what the user wanted.

See also commit 6bdfbc4cb (libbb: fix '--help' handling in
FEATURE_SH_NOFORK=y).
