+##
+## when we say this array stores "parsed" cspecs, we actually mean the cspecs
+## have been parsed and indexed by command names in this array; cspec strings
+## themselves have no difference between this array and `_raw_vanilla_cspecs`;
+##
+## example:
+##

+## a set of raw vanilla completions, keyed by cspec; these raw cspecs will be
+## parsed and loaded into `_vanilla_cspecs` on use; we need this lazy loading
+## because parsing all cspecs on sourcing incurs a large performance overhead;
+##
+## vanilla completions are alias-free and fetched before `_complete_alias` is
+## set as the completion function for alias commands; the way we enforce this
+## partial order is to init this array on source; the sourcing happens before
+## `complete -F _complete_alias ...` for obvious reasons;
+##
+## this is made a set, not an array, to avoid duplication when this script is
+## sourced repeatedly; each sourcing overwrites previous ones on duplication;

+## - git repo ;
+## - commit `ce23728687ce9e584333367075c9deef413553fa`;
+## - function `bashline.c:attempt_shell_completion`;
+## - function `bashline.c:find_cmd_end`;
+## - function `bashline.c:find_cmd_start`;
+## - function `pcomplete.c:command_line_to_word_list`;
+## - function `pcomplete.c:programmable_completions`;
+## - function `subst.c:skip_to_delim`;
+## - function `subst.c:split_at_delims`;
+##
+## this function shall give similar result as `bash` reference implementation
+## for common use cases, but will not strive for full compatibility, which is
+## too complicated when written in bash; we will support additional use cases
+## as they show up and prove worthy;
+##
+## another reason we not pursue full compatibility is, even bash itself fails
+## on some use cases, such as `ping 2>&1` and `ping &>/dev/null`; ironically,
+## if we define an alias and complete using `_complete_alias`, then it works:
+##
+## $ alias ping='ping 2>&1'
+## $ complete -F _complete_alias ping
+## $ ping
+## {ip}
+## {ip}
+## {ip}
+##
+## backslash: a non-quoted backslash (`\`) preserves the literal value of the
+## next character that follows with the exception of ``; a backslash
+## enclosed in single quotes loses such special meaning; a backslash enclosed
+## in double quotes retains such special meaning only when followed by one of
+## the following (5) characters:
+##
+## $ ` " \
+##
+## we do not allow `` in alias body; this simplifies our argument: a
+## non-quoted backslash always preserves next character; a backslash enclosed
+## in double quotes only preserves the above 4 characters (minus ``);
+##
+## when a command substitution is enclosed in double quotes, backslash within
+## the command substitution may retain such special meaning, despite whatever
+## bash manual says; compare:
+##
+## "`\"`"
+## "$(\")"
+##
+## in the first form the backslash is not literal even though not followed by
+## characters mentioned in section command substitution, bash manual; we will
+## not handle backquote correctly in this case; as an advice, avoid backquote;
+##
+## warn: the output of this function is *not* a faithful split of the input;
+## this function drops redirections and assignments, and only keeps the last

+## support commmand substitutions, etc.; if you run its output as argv, then
