Colin Watson	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.
