10fc746e6d if HAVE_VASPRINTF (set ifdef BSD4_4), use vasprintf() instead of homegrown
code in doformat().  results in slightly smaller /bin/sh.  idea suggested by
Witold J. Wnuk <witek@pd37.warszawa.sdi.tpnet.pl>, approved by christos.

dd7296f47a support %ll (as synonym for %q) in doformat(), since my changes to %q -> %ll
broke this :/

84d782a52f __CONCAT does token pasting, not string concatnation. if something like:
__CONCAT("PATH=",_PATH_STDPATH);
actually works to concantate strings, it's because the preprocessor expands
it into "PATH=""whatever _PATH_STDPATH is" as separate strings, and then
ANSI string concatenation is performed on that.  It's more straightforward
to just use ANSI string concatenation directly, and newer GCCs complain
(rightly) about mis-use of token pasting.

8e2797bc1e PR/11283: Hubert Feyrer: random memory corruption executing commands:
Fix from FreeBSD:

    growstackblock() sometimes relocates a stack_block considered empty
    without properly relocating stack marks referencing that block.
    The first call to popstackmark() with the unrelocated stack mark
    as argument then causes sh to abort.

    Relocating the relevant stack marks seems to solve this problem.

    The patch changes the semantics of popstackmark() somewhat.  It can
    only be called once after a call to setstackmark(), thus cmdloop() in
    main.c needs an extra call to setstackmark().

2a1ee59131 un-__P functions declared in parser.h. host programs include parser.h,

not declaring the parser functions in headers used by host programs,
but this works well enough.)

2806df576c It turns out that the code disabled in revision 1.30 *does* have an important
function (which nobody was able to explain): it's critical to allowing a
complex command run from an interactive shell to be terminated.  So, reinstate
it and fix it correctly.  See the comment if you really want the gory details.
