For example: -** pattern: -*-*-*-*-*-*-12-*-*-*-m-*-*-* -** text 1: -adobe-courier-bold-o-normal--12-120-75-75-m-70-iso8859-1 -** text 2: -adobe-courier-bold-o-normal--12-120-75-75-X-70-iso8859-1 -** Text 1 matches with 51 calls, while text 2 fails with 54 calls. Without -** the ABORT code, it takes 22310 calls to fail. Ugh. The following -** explanation is from Lars: -** The precondition that must be fulfilled is that DoMatch will consume -** at least one character in text. This is true if *p is neither '*' nor -** '\0'.) The last return has ABORT instead of FALSE to avoid quadratic -** behaviour in cases like pattern "*a*b*c*d" with text "abcxxxxx". With -** FALSE, each star-loop has to run to the end of the text; with ABORT -** only the last one does. -** -** Once the control of one instance of DoMatch enters the star-loop, that -** instance will return either TRUE or ABORT, and any calling instance -** will therefore return immediately after (without calling recursively -** again). In effect, only one star-loop is ever active. It would be -** possible to modify the code to maintain this context explicitly, -** eliminating all recursive calls at the cost of some complication and -** loss of clarity (and the ABORT stuff seems to be unclear enough by -** itself).
