f463d9da76 • revert the cat hack for realpath and rename 
‣ I was convinced by several that more magic is never the solution
• fix a comment: function cat already had precedence
• change cat loader to look for existence, FPATH included, before
  ditching the builtin; note that in manpage

cad9bc86d3 Implement the “FKSH functions have local scope for shell options” feature

While here, tweak build scripts a bit, fixup MirBSD-specific Makefile
things, remove part of a comment that’s uninteresting.

e1cda74d04 SECURITY: fix integer overflows related to file descriptor parsing 
bug initially found by Pawel Wylecial (LP#1440685)
additional bug found and suggested fix by enh (elliott hughes)

This commit also renames struct ioword.flag to ioflag to disambiguate
it from other members named “flag”, changes it to an unsigned type,
and packs ioflag and unit into shorts each, to make the struct smaller
(aligned even: 16 bytes on 32-bit systems) and reviews some of the
code involved in fd handling, though there wasn’t much to be found.

1248a0a521 basically unbreak use of $*/$@ in here documents 
a bit funny:
with NUL IFS, $* behaves like dash ('ab') and $@ like bash/ksh93 ('a b')

with WS or NWS IFS, all shells behave alike though

2f52b993a1 • Build.sh: fix NSIG detection for gcc-snapshot

  hopefully, Coverity Scan/Prevent

• eval.c: fix tilde_ok data type (only unsigned may shl constantly)
• exec.c: fix shebang buf array accesses to always go via uint8_t *

033e1f4b9e fix LP#1277691 (“nameref RHS not syntax checked”) and the inability to 
use errorf() while nameref states were being changed (by almost completely
eliminating the global variable) and the readonly first array variable
bypass (typo/refactoro); also, whitespace, one int → bool, and add a
comment wrt. the parser rewrite talked about with igli during a fever ;)
