3963d943f8 ash: refresh stack pointers after makestrspace in rmescapes 
Without this, rmescapes sometimes returns random garbage while
performing parameter expansions such as ${foo#bar}, in the event that
the allocation of r happens to need to reallocate the stack and hence
invalidate str and p.  I'd love to provide a test case but unfortunately
it's dependent on exact stack layout, so I don't have anything simpler
than the situation described in
https://bugs.launchpad.net/ubuntu/+source/partman-base/+bug/527401/comments/23
which involved a sequence of foo="${foo#*, }" expansions on a long
string inside our RAID configuration tool.

The same fix has been in dash since 2007-09-26, contributed by Roy
Marples <uberlord@gentoo.org>.  I actually came up with it independently
almost to the character, but then synced it up with the variable naming
used in dash when I noticed that change afterwards.

920185c69a cmp: remove history comment. it is more natural to keep it in source control 
The comment was:

* Mar 16, 2003      Manuel Novoa III   (mjn3@codepoet.org)
*
* Original version majorly reworked for SUSv3 compliance, bug fixes, and
* size optimizations.  Changes include:
* 1) Now correctly distinguishes between errors and actual file differences.
* 2) Proper handling of '-' args.
* 3) Actual error checking of i/o.
* 4) Accept SUSv3 -l option.  Note that we use the slightly nicer gnu format
*    in the '-l' case.
