283 - How many unique completions have been generated, to terminate

285 so large as to be useless. This helps avoid GDB seeming to lock
286 up in the event the user requests to complete on something vague
287 that necessitates the time consuming expansion of many symbol
288 tables.
289
290 - The completer's idea of least common denominator (aka the common
291 prefix) between all completion matches to hand over to readline.
292 Some completers provide matches that don't start with the
293 completion "word". E.g., completing on "b push_ba" on a C++
294 program usually completes to std::vector<...>::push_back,
295 std::string::push_back etc. If all matches happen to start with
296 "std::", then readline would figure out that the lowest common
297 denominator is "std::", and thus would do a partial completion
298 with that. I.e., it would replace "push_ba" in the input buffer
299 with "std::", losing the original "push_ba", which is obviously
300 undesirable. To avoid that, such completers pass the substring
301 of the match that matters for common denominator computation as
302 MATCH_FOR_LCD argument to add_completion. The end result is
303 passed to readline in gdb_rl_attempted_completion_function.
304
305 - The custom word point to hand over to readline, for completers
306 that parse the input string in order to dynamically adjust
307 themselves depending on exactly what they're completing. E.g.,
308 the linespec completer needs to bypass readline's too-simple word
309 breaking algorithm.
