199 * These argument-breaking rules apply to Visual Studio 7, which
200 * is currently the compiler expected to be used for PuTTY. Visual
201 * Studio 10 has different rules, lacking the curious mod 3
202 * behaviour of consecutive quotes described below; I presume they
203 * fixed a bug. As and when we migrate to a newer compiler, we'll
204 * have to adjust this to match; however, for the moment we
205 * faithfully imitate in our GUI utilities what our CLI utilities
206 * can't be prevented from doing.
208 * When I investigated this, at first glance the rules appeared to
211 * - Single quotes are not special characters.
213 * - Double quotes are removed, but within them spaces cease
216 * - Backslashes are _only_ special when a sequence of them
217 * appear just before a double quote. In this situation,
218 * they are treated like C backslashes: so \" just gives a
219 * literal quote, \\" gives a literal backslash and then
220 * opens or closes a double-quoted segment, \\\" gives a
221 * literal backslash and then a literal quote, \\\\" gives
222 * two literal backslashes and then opens/closes a
223 * double-quoted segment, and so forth. Note that this
224 * behaviour is identical inside and outside double quotes.
226 * - Two successive double quotes become one literal double
227 * quote, but only _inside_ a double-quoted segment.
228 * Outside, they just form an empty double-quoted segment
229 * (which may cause an empty argument word).
231 * - That only leaves the interesting question of what happens
232 * when one or more backslashes precedes two or more double
233 * quotes, starting inside a double-quoted string. And the
234 * answer to that appears somewhat bizarre. Here I tabulate
235 * number of backslashes (across the top) against number of
236 * quotes (down the left), and indicate how many backslashes
237 * are output, how many quotes are output, and whether a
238 * quoted segment is open at the end of the sequence:
244 * 0 0,0,y | 1,0,y 2,0,y 3,0,y 4,0,y
245 * --------+-----------------------------
246 * 1 0,0,n | 0,1,y 1,0,n 1,1,y 2,0,n
247 * q 2 0,1,n | 0,1,n 1,1,n 1,1,n 2,1,n
248 * u 3 0,1,y | 0,2,n 1,1,y 1,2,n 2,1,y
249 * o 4 0,1,n | 0,2,y 1,1,n 1,2,y 2,1,n
250 * t 5 0,2,n | 0,2,n 1,2,n 1,2,n 2,2,n
251 * e 6 0,2,y | 0,3,n 1,2,y 1,3,n 2,2,y
252 * s 7 0,2,n | 0,3,y 1,2,n 1,3,y 2,2,n
253 * 8 0,3,n | 0,3,n 1,3,n 1,3,n 2,3,n
254 * 9 0,3,y | 0,4,n 1,3,y 1,4,n 2,3,y
255 * 10 0,3,n | 0,4,y 1,3,n 1,4,y 2,3,n
256 * 11 0,4,n | 0,4,n 1,4,n 1,4,n 2,4,n
259 * [Test fragment was of the form "a\\\"""b c" d.]
261 * There is very weird mod-3 behaviour going on here in the
262 * number of quotes, and it even applies when there aren't any
263 * backslashes! How ghastly.
265 * With a bit of thought, this extremely odd diagram suddenly
266 * coalesced itself into a coherent, if still ghastly, model of
269 * - As before, backslashes are only special when one or more
270 * of them appear contiguously before at least one double
271 * quote. In this situation the backslashes do exactly what
272 * you'd expect: each one quotes the next thing in front of
273 * it, so you end up with n/2 literal backslashes (if n is
274 * even) or (n-1)/2 literal backslashes and a literal quote
275 * (if n is odd). In the latter case the double quote
276 * character right after the backslashes is used up.
278 * - After that, any remaining double quotes are processed. A
279 * string of contiguous unescaped double quotes has a mod-3
282 * * inside a quoted segment, a quote ends the segment.
283 * * _immediately_ after ending a quoted segment, a quote
284 * simply produces a literal quote.
285 * * otherwise, outside a quoted segment, a quote begins a
288 * So, for example, if we started inside a quoted segment
289 * then two contiguous quotes would close the segment and
290 * produce a literal quote; three would close the segment,
291 * produce a literal quote, and open a new segment. If we
292 * started outside a quoted segment, then two contiguous
293 * quotes would open and then close a segment, producing no
294 * output (but potentially creating a zero-length argument);
295 * but three quotes would open and close a segment and then
296 * produce a literal quote.
300 * First deal with the simplest of all special cases: if there
301 * aren't any arguments, return 0,NULL,NULL.
