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.
"|" is now found properly by looking for words that come
from the lexical analyser, rather than hacking a pattern
returned in one dollop.
Update some completion functions that need extra quoting
as a result.
Add test for new parsing.
Update version number to 5.0.8-dev-3 because of wordcode
incompatibility.
Handled generally, though only showing up in special nested
cases.
Also fix ZLE so it doesn't cancel the interrupt flag when
not actually returning from a local keymap.
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.
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.
restrict token aliasing (34641) to global aliases; tighten up POSIX_ALIASES to better match spec; update Aliasing doc to cover this and clarify older behavior

* 34723: configure.ac: turn off fixed site function directory if
Mark arithmetic substitutions with tokens to make sure the substitution
go knows what to do. Before it was guessing by counting the
parentheses at the end.
Garbage input (nul bytes, etc.) can cause the $(...) parser to become
confused during look-ahead and attempt to back up the input too far.
This commit catches the error but does not fix the underlying cause.
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.
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.
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.
