8623c59aca Revert previous commit that fixes PR/36079 (shell misses exit trap), because 
the fix causes $! to point to the wrong process in pipelines, which is worse.

3f6e3bc032 In foo="echo \"hi\"", the backslashes should be removed by the outer 
double quotes, not seen by the inner backquotes.  Previously, ksh(1)
handled this correctly in non-posix mode but incorrectly in posix mode.

The previous comments in src/bin/ksh/lex.c quote parts of some version
of the POSIX specification.  The version of POSIX being quoted is not
identified, but the wording is very similar to that in SUSv3
<http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html>.

It seems clear that the words "having escape characters removed"
mean, in that context, that the backslash before the double quote in
"...`...\"...`..." is removed as part of the handling of the outer
double quotes, so that the backslash is not present when the inner
backquotes are handled.  The new code in this commit follows this
interpretation.  The previous code followed a different interpretation
which is now believed to be incorrect.

Discussed in tech-userlevel.  Closes PR 26493.

7fb5a8c68e The field width passed for a %.*s printf format is supposed to be int, not 
ptrdiff_t; on 64-bit platforms the latter will be too wide.

744c8edc4b Wrap declaration of a STATIC function that's only conditionally defined

(In the long run STATIC should go away - it might have once been a
portability hack but now definitely serves no purpose.)
