* - Rewrite the code to implement the simpler solution explained above :-)
*/
+/* Regex search:
+ *
+ * With a regex, we don't know how many lines a match can span. A regex will
+ * most probably match only one line, but a regex can contain something like
+ * "\n*", or the dot metacharacter can also match newlines, with the "?s" option
+ * (see G_REGEX_DOTALL).
+ * Therefore a simple solution is to always begin the search at the beginning of
+ * the document. Only the scan_region is taken into account for scanning the
+ * buffer.
+ *
+ * For non-regex searches, when there is an insertion or deletion in the buffer,
+ * we don't need to re-scan all the buffer. If there is an unmodified match in
+ * the neighborhood, no need to re-scan it. For a regex search, it is more
+ * complicated. An insertion or deletion outside a match can modify a match
+ * located in the neighborhood. Take for example the regex "(aa)+" with the
+ * buffer contents "aaa". There is one occurrence: the first two letters. If we
+ * insert an extra 'a' at the end of the buffer, the occurrence is modified to
+ * take the next two letters. That's why the buffer is re-scanned entirely on
+ * each insertion or deletion in the buffer.
+ *
+ * For searching the matches, the easiest solution is to retrieve all the buffer
+ * contents, and search the occurrences on this big string. But it takes a lot
+ * of memory space. It is better to do multi-segment matching, also called
+ * incremental matching. See the pcrepartial(3) manpage. The matching is done
+ * segment by segment, with the G_REGEX_MATCH_PARTIAL_HARD flag (for reasons
+ * explained in the manpage). We begin by the first segment of the buffer as the
+ * subject string. If a partial match is returned, we append the next segment to
+ * the subject string, and we try again to find a complete match. When a
+ * complete match is returned, we must continue to search the next occurrences.
+ * The max lookbehind of the pattern must be retrieved. The start of the next
+ * subject string is located at max_lookbehind characters before the end of the
+ * previously found match. Similarly, if no match is found (neither a complete
+ * match nor a partial match), we take the next segment, with the last
+ * max_lookbehind characters from the previous segment.
+ *
+ * TODO/idea:
+ * What we would like to support in applications is the incremental search:
+ * while we type the pattern, the buffer is scanned and the matches are
+ * highlighted. When the pattern is not fully typed, strange things can happen,
+ * including a pattern that match the entire buffer. And if the user is
+ * working on a really big file, catastrophe: the UI is blocked!
+ * To avoid this problem, a solution is to search the buffer differently
+ * depending on the situation:
+ * - First situation: the subject string to scan is small enough, we retrieve it
+ * and scan it directly.
+ * - Second situation: the subject string to scan is too big, it will take
+ * too much time to retrieve it and scan it directly. We handle this situation
+ * in three phases: (1) retrieving the subject string, chunks by chunks, in
+ * several idle loop iterations. (2) Once the subject string is retrieved
+ * completely, we launch the regex matching in a thread. (3) Once the thread
+ * is finished, we highlight the matches in the buffer. And voilà.
+ *
+ * Known issue:
+ * To search at word boundaries, \b is added at the beginning and at the
+ * end of the pattern. But \b is not the same as
+ * gtk_text_iter_starts_word() and gtk_text_iter_ends_word(). \b for
+ * example doesn't take the underscore as a word boundary.
+ * Using gtk_text_iter_starts_word() and ends_word() for regex searches
+ * is not easily possible: if the GRegex return a match, but doesn't
+ * start and end a word, maybe a shorter match (for a greedy pattern)
+ * start and end a word, or a longer match (for an ungreedy pattern). To
+ * be able to use the gtk_text_iter_starts_word() and ends_word()
+ * functions for regex search, g_regex_match_all_full() must be used, to
+ * retrieve _all_ matches, and test the word boundaries until a match is
+ * found at word boundaries.
