3459 * These argument-breaking rules apply to Visual Studio 7, which
3460 * is currently the compiler expected to be used for the Windows
3461 * port of my puzzles. Visual Studio 10 has different rules,
3462 * lacking the curious mod 3 behaviour of consecutive quotes
3463 * described below; I presume they fixed a bug. As and when we
3464 * migrate to a newer compiler, we'll have to adjust this to
3465 * match; however, for the moment we faithfully imitate in our GUI
3466 * utilities what our CLI utilities can't be prevented from doing.
3467 *
3468 * When I investigated this, at first glance the rules appeared to
3469 * be:
3470 *
3471 * - Single quotes are not special characters.
3472 *
3473 * - Double quotes are removed, but within them spaces cease
3474 * to be special.
3475 *
3476 * - Backslashes are _only_ special when a sequence of them
3477 * appear just before a double quote. In this situation,
3478 * they are treated like C backslashes: so \" just gives a
3479 * literal quote, \\" gives a literal backslash and then
3480 * opens or closes a double-quoted segment, \\\" gives a
3481 * literal backslash and then a literal quote, \\\\" gives
3482 * two literal backslashes and then opens/closes a
3483 * double-quoted segment, and so forth. Note that this
3484 * behaviour is identical inside and outside double quotes.
3485 *
3486 * - Two successive double quotes become one literal double
3487 * quote, but only _inside_ a double-quoted segment.
3488 * Outside, they just form an empty double-quoted segment
3489 * (which may cause an empty argument word).
3490 *
3491 * - That only leaves the interesting question of what happens
3492 * when one or more backslashes precedes two or more double
3493 * quotes, starting inside a double-quoted string. And the
3494 * answer to that appears somewhat bizarre. Here I tabulate
3495 * number of backslashes (across the top) against number of
3496 * quotes (down the left), and indicate how many backslashes
3497 * are output, how many quotes are output, and whether a
3498 * quoted segment is open at the end of the sequence:
3499 *
3500 * backslashes
3501 *
3502 * 0 1 2 3 4
3503 *
3504 * 0 0,0,y | 1,0,y 2,0,y 3,0,y 4,0,y
3505 * --------+-----------------------------
3506 * 1 0,0,n | 0,1,y 1,0,n 1,1,y 2,0,n
3507 * q 2 0,1,n | 0,1,n 1,1,n 1,1,n 2,1,n
3508 * u 3 0,1,y | 0,2,n 1,1,y 1,2,n 2,1,y
3509 * o 4 0,1,n | 0,2,y 1,1,n 1,2,y 2,1,n
3510 * t 5 0,2,n | 0,2,n 1,2,n 1,2,n 2,2,n
3511 * e 6 0,2,y | 0,3,n 1,2,y 1,3,n 2,2,y
3512 * s 7 0,2,n | 0,3,y 1,2,n 1,3,y 2,2,n
3513 * 8 0,3,n | 0,3,n 1,3,n 1,3,n 2,3,n
3514 * 9 0,3,y | 0,4,n 1,3,y 1,4,n 2,3,y
3515 * 10 0,3,n | 0,4,y 1,3,n 1,4,y 2,3,n
3516 * 11 0,4,n | 0,4,n 1,4,n 1,4,n 2,4,n
3517 *
3518 *
3519 * [Test fragment was of the form "a\\\"""b c" d.]
3520 *
3521 * There is very weird mod-3 behaviour going on here in the
3522 * number of quotes, and it even applies when there aren't any
3523 * backslashes! How ghastly.
3524 *
3525 * With a bit of thought, this extremely odd diagram suddenly
3526 * coalesced itself into a coherent, if still ghastly, model of
3527 * how things work:
3528 *
3529 * - As before, backslashes are only special when one or more
3530 * of them appear contiguously before at least one double
3531 * quote. In this situation the backslashes do exactly what
3532 * you'd expect: each one quotes the next thing in front of
3533 * it, so you end up with n/2 literal backslashes (if n is
3534 * even) or (n-1)/2 literal backslashes and a literal quote
3535 * (if n is odd). In the latter case the double quote
3536 * character right after the backslashes is used up.
3537 *
3538 * - After that, any remaining double quotes are processed. A
3539 * string of contiguous unescaped double quotes has a mod-3
3540 * behaviour:
3541 *
3542 * * inside a quoted segment, a quote ends the segment.
3543 * * _immediately_ after ending a quoted segment, a quote
3544 * simply produces a literal quote.
3545 * * otherwise, outside a quoted segment, a quote begins a
3546 * quoted segment.
3547 *
3548 * So, for example, if we started inside a quoted segment
3549 * then two contiguous quotes would close the segment and
3550 * produce a literal quote; three would close the segment,
3551 * produce a literal quote, and open a new segment. If we
3552 * started outside a quoted segment, then two contiguous
3553 * quotes would open and then close a segment, producing no
3554 * output (but potentially creating a zero-length argument);
3555 * but three quotes would open and close a segment and then
3556 * produce a literal quote.
