cfc06203e7 Add new functions flag -V/--inherit-variable
--inherit-variable takes a variable name and snapshots its current
value. When the function is executed, it will have a local variable with
this value already defined. Printing the function source will include
synthesized `set -l` lines for the values.

This is primarily useful for functions that are created on the fly, such
as in `psub`.

d67800bbce Make false/true into builtins
Making `true` into a builtin is a significant optimization to `while
true` loops. As long as `true` is a builtin, we may as well make `false`
builtin as well (despite the fact that it's not typically executed in a
loop).

0a3f220572 Rework mode handling of bind
Binds with the same sequence in multiple modes was not working right.
Fix up the implementation to propagate modes everywhere as necessary.
This means that `bind` will properly list distinct binds with the same
sequence, and `bind -e` will take mode into account properly as well.
Note that `bind -e seq` now assumes the bind is in the default bind
mode, whereas before it would erase the first binding with that sequence
regardless of mode.

`bind -e -a` still erases all binds in all modes, though `bind -M mode
-e -a` still only erases all binds in the selected mode.

without specifyign `-k`. Oops.

a012aedb31 Fix incorrect error on read with 1-character input
When `read` is given a single character of input (including the
newline), it was bailing as if it had been given no input. This is
incorrect.

8f8c4cdd17 Implement new read --null flag
The `--null` flag to `read` makes it split incoming lines on NUL instead
of newlines. This is intended for processing the output of a command
that uses NUL separators (such as `find -print0`).

Fixes #1694.

1f3a93a3af
Fix the compilation under gcc 4.9.0.
gcc interpretes C99's compound literals more strictly by invalid the
compound literal on implicit to pointer cast (because of automatic
storage duration, 6.5.2.5.6 in C99 standard draft).

This fixes the issue by not using compound literals at all.

06400b83b1 Support for command wrapping ("aliases")
Add the --wraps option to 'complete' and 'function'. This allows a
command to (recursively) inherit the completions of a wrapped command.
Fixes #393.

When evaluating a completion, we inspect the entire "wrap chain" for a
command, i.e. we follow the sequence of wrapping until we either hit a
loop (which we silently ignore) or the end of the chain. We then
evaluate completions as if the wrapping command were substituted with
the wrapped command. Currently this only works for commands, i.e.
'complete --command gco --wraps git\ checkout' won't work (that would
seem to encroaching on abbreviations anyways). It might be useful to
show an error message for that case.

The commandline builtin reflects the commandline with the wrapped
command substituted in, so e.g. git completions (which inspect the
command line) will just work. This sort of command line munging is
also performed by 'complete -C' so it's not totally without precedent.

'alias will also now mark its generated function as wrapping the
'target.

973dd6ffbd read: Support arrays, character splitting
Enhance the `read` builtin to support creating an array with the --array
flag. With --array, only a single variable name is allowed and the
entire input is tokenized and placed into that variable as an array.

Also add custom behavior if IFS is empty or unset. In that event, split
the input on every character, instead of the previous behavior of doing
no splitting at all.
