86229fdf09 36468: Fix infinite loop exiting from Zle widget. 
If the exit was while we were waiting to complete a lexical expression
we might not exit from the loop.

f1923bdfa6 Add non-metafied character length handling. 
Use this in regex module and add test using $'\ua0'.

Rename mb_metacharinit() to mb_charinit() as it does not involve
metafied characters.

f1c702f2a4 34817: Catch some errors earlier when reading history. 
Mostly for the case of an interrupt.

Don't try to process words when we know something's gone wrong.

Also abort history reading earlier on an interrupt.

4fb669a72d 34758: fix yet more history / command subst interaction. 
In general we need to wind back over the history text input
inside command substitution because there's no level of
the input mechanism between history and the lexer.

4688de1677 34365: History lockfile backoff: randomised time. 
Time doubles on each lock failure.

zsleep() provides microsecond resolution for sleep; uses nanosleep() if
available, else select via means of existing tty poll function.

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.

979f72199f 32580: avoid indefinite wait in lockhistfile() by checking for lock file time stamp in the future 
Also change behavior of HIST_FCNTL_LOCK to use only fcntl() locking, rather
than applying both kinds of lock.

ff520d1b79 31823: add HISTORY_IGNORE parameter

history from the HISTFILE at write time.

d0fe73c5fb 31815: another fix for INCAPPENDHISTORY change. 
We need to save immediately if something is pushed on the history stack
to ensure we use the right file before popping.

8ffdf161c7 31797: to match documentation, avoid expanding history when there is neither a 
word nor an event designator

There are still a few cases where expansion is attempted even though the
documentation indicates it will not be, but in most of those cases the
expansion will fail.  The now-fixed case would fall back to default
expansion of the previous command.

6f195241f3 31794: further refinement to INCAPPENDHISTORY change. 
With SHAREHISTORY we should make sure the code behaves as it always
did, because it takes care about locking a file once for reading
and writing.

e282fd8ecb 31750: fix for HISTREDUCEBLANKS option.

non-white-space text, which is probably comments.
