PATCH: _regex_arguments, _apt_arguments and _apt-get
- X-seq: zsh-workers 7720

I tried to modify _apt-get to perfection.
Since `apt' has slightly peculiar command line parsing library, I
decide to make and use the function `_regex_arguments' more primitive
and powerful than `_arguments'.

+## usage: _regex_arguments funcname regex
+
+# _regex_arguments compiles `regex' and emit the result of the state
+# machine into the function `funcname'. `funcname' parses a command line
+# according to `regex' and evaluate appropriate actions in `regex'. Before
+# parsing the command line string is genereted by concatinating `words'
+# (before `PREFIX') and `PREFIX' with a separator NUL ($'\0').
+
+# The `regex' is defined as follows.
+
+## regex word definition:
+
+# elt-pattern = "/" ( pattern | "[]" ) # cutoff
+# | "%" pattern # non-cutoff
+# lookahead = "@" pattern
+# parse-action = "-" zsh-code-to-eval
+# complete-action = "!" zsh-code-to-eval
+
+## regex word sequence definition:
+
+# element = elt-pattern [ lookahead ] [ parse-action ] [ complete-action ]
+#
+# regex = element
+# | "(" regex ")"
+# | regex "#"
+# | regex regex
+# | regex "|" regex
+# | void
+# | null
+#
+# NOTE: void and null has no explicit representation. However null can
+# be represent with empty words such as \( \).
+
+# example: (in zsh quoted form)
+
+# $'[^\0]#\0' \# : zero or more words
+
+## auxiliary functions definition:
+
+# fst : a * b -> a
+# snd : a * b -> b
+# fst( (x, y) ) = x
+# snd( (x, y) ) = y
+
+# nullable : regex -> bool
+# first : regex -> list of element
+# match : string * list of element -> element + {bottom}
+# right : string * element -> string
+# left : string * element -> string
+# next : regex * element -> regex + {bottom}
+# trans : string * string * regex -> (string * string * regex) + {bottom}
+
+# nullable(void) = false
+# nullable(null) = true
+# nullable(e) = false
+# nullable(r #) = true
+# nullable(r1 r2) = nullable(r1) and nullable(r2)
+# nullable(r1 | r2) = nullable(r1) or nullable(r2)
+
+# first(void) = {}
+# first(null) = {}
+# first(e) = [ e ]
+# first(r #) = first(r)
+# first(r1 r2) = nullable(r1) ? first(r1) ++ first(r2) : first(r1)
+# first(r1 | r2) = first(r1) ++ first(r2)
+
+# match(s, []) = bottom
+# match(s, [e1, e2, ...]) = e if [[ $s = $elt-pattern[e]$lookahead[e]* ]]
+# | match(s, [e2, ...]) otherwise
+
+# right(s, e) = ${s##$elt-pattern[e]}
+# left(s, e) = ${(M)s##$elt-pattern[e]}
+
+### XXX: It can treat lookaheads if zsh provide $1, $2, ... in perl.
+
+# next(void, e) = bottom
+# next(null, e) = bottom
+# next(e1, e0) = e1 eq e0 ? null : bottom # eq is test operator of identity equality.
+# next(r #, e) = next(r, e) != bottom ? next(r, e) (r #) : bottom
+# next(r1 r2, e) = next(r1, e) != bottom ? next(r1, e) r2 : next(r2, e)
+# next(r1 | r2, e) = next(r1, e) != bottom ? next(r1, e) : next(r2, e)
+
+# trans( (t, s, r) ) = ( (cutoff(e) ? '' : t ++ left(s, e)), right(s, e), next(r, e) )
+# where e = match(s, first(r))
+
+# NOTE: This `next' definition is slightly different to ordinaly one.
+# This definition uses only one element of first(r) for transition
+# instead of all elements of first(r).
+
+# If _regex_arguments takes the regex r0, the first state of the state
+# machine is r0. The state of the state machine transit as follows.
+
+# ('', s0, r0) -> trans('', s0, r0) = (t1, s1, r1) -> trans(t1, s1, r1) -> ...
+
+# If the state is reached to bottom, the state transition is stopped.
+
+# ... -> (tN, sN, rN) -> bottom
+
+# For each transitions (tI, sI, rI) to trans(tI, sI, rI), the state
+# machine evaluate parse-action bound to match(sI, first(rI)).
+
+# In parse-action bound to match(sI, first(rI)) = e, it can refer variables:
+# _ra_left : tI+1
+# _ra_match : left(sI, e)
+# _ra_right : sI+1
+
+# If the state transition is stopped, the state machine evaluate
+# complete-actions bound to first(rN) if tN and sN does not contain NUL.
+# When complete-actions are evaluated, completion focus is restricted to
+# tN ++ sN. (This is reason of tN and sN cannot contain NUL when
+# completion.)
+# Also, if there are last transitions that does not cut off the string
+# (tJ ++ sJ = tJ+1 ++ sJ+1 = ... = tN-1 ++ sN-1 = tN ++ sN),
+# complete-actions bound to them
+# --- match(sJ, first(rJ)), ..., match(sN-1, first(rN-1)) --- are also
+# evaluated before complete-actions bound to first(rN).
+
+# example:
+
+# compdef _tst tst
+
+# _regex_arguments _tst /$'[^\0]#\0' /$'[^\0]#\0' '!compadd aaa'
+# _tst complete `aaa' for first argument.
+# First $'[^\0]#\0' is required to match with command name.
+
+# _regex_arguments _tst /$'[^\0]#\0' \( /$'[^\0]#\0' '!compadd aaa' /$'[^\0]#\0' !'compadd bbb' \) \#
+# _tst complete `aaa' for (2i+1)th argument and `bbb' for (2i)th argument.
+
+# _regex_arguments _tst /$'[^\0]#\0' \( /$'[^\0]#\0' '!compadd aaa' \| /$'[^\0]#\0' !'compadd bbb' \) \#
+# _tst complete `aaa' or `bbb'.
