2654cb43f6 36651: WARN_CREATE_GLOBAL += math expressions 
Without this, '() { (( x=42 )) }' and '() { for (( i=0; … )) }' wouldn't warn
about $x and $i, respectively, being created global.

9958684574 36022 fix bug that some loop constructs could not be interrupted, revise signal queueing 
There are two underlying ideas here:  (1) Keeping signals queued around
anything that's doing memory management (including push/pop of the heap)
has become crucial.  (2) Anytime the shell is going to run a command, be
it buitin or external, it must be both safe and necessary to process any
queued signals, so that the apparent order of signal arrival and command
execution is preserved.

Peter Stephenson
39b28980f3 various posts: Implement assignment parsing for typeset. 
Typeset assignments now work like raw assignments except
for no "+=" and no GLOB_ASSIGN.

Documented in typeset builtin doc and mentioned in release notes.

Tests to ensure basic sanity.

Enabled by default, can be turned off by "disable -r" with typeset
family of commands.

2b08d0ed67 35318: POSIX_BUILTINS behaviour for getopts. 
It needs to keep OPTIND, as well as the index within the
string pointed to by OPTIND, global in this case.

2f6a8a6c6c Tweak test for function level of exit. 
Sometimes local level jumps so we need an inequality instead
of an equality.

df5115a741 34979: Preserve job text when doing shell job fix. 
This handles list_pipe_text in execlist() along with other
variables that are saved and restored and, in the special
case of source, cleared.

3bf8cab82e 34900: assignment before an "exec".

a2c579050f 34887: Fix POSIX_BUILTINS with assignment. 
In the form
  var=val command special-builtin-or-func
the var is restored after execution, unlike the case where "command"
is absent.

Clear up case in code that handles this.

Add tests.

da86d6b4f2 34485: More rationalisation for anonymous functions. 
Don't attempt to treat as "simple" case as there are too many
hidden problems.

Pull out some post-execution functions to a common case in
execcmd().

c6c9f5daf2 34322: bug with interface to parsestr() etc. 
Was showing up in places like ${(e)...} where command substitution
could reallocate the token string, but actually there was never any
guarantee that the lexer wouldn't do that, so this was always
a bit iffy.

cfd91eac07 Rearrange context saving. 
Variables are now associated with the module that declares them, being
initialised and saved/restored there.  However, as many variables are
used for communication between modules, many of them are set in multiple
places, so the assignment is ambiguous.

d067ebcacd 33876: etc.: Separate errors and keyboards interrupts 
Combination of 12 commits from interrupt_abort branch.

Basic strategy is to introduce bits to errflag and to set and
reset them separately.

Remove interrupt status on return to main keymap.

Turn off ERRFLAG_INT for always block.

Restore bit thereafter: we probably need a new variable in order
to allow user interrupts to be reset in the always block.

Add TRY_BLOCK_INTERRUPT

This works the same as TRY_BLOCK_ERROR, but for a SIGINT, too.

Ensure propagation of SIGINT from exited job.

If received by foreground job, shell uses ERRFLAG_INT, not
ERRFLAG_ERROR, to set the new state.

Reset errflag before precmd()

Add always block in _main_completion to fix ZLS_COLORS

Ensures we get the right state of $ZLS_COLORS at the end of _main_complete
even if there's an interrupt.  However, the "right state" is a bit messy
as it depends on styles.
