971  * find out the matching composition mappings if any and return the address
972  * to the composition mappings as explained in the do_composition().
1060  * do necessary canonical composition and then copy over the result back to
1100 		 * have any chance to do composition and so we just copy them  in do_composition()
1150 		 * Let's then find out if this Starter has composition  in do_composition()
1158 		 * We have a Starter with composition mapping and the next  in do_composition()
1160 		 * we can do composition.  in do_composition()
1176 		 * The composition final table entry pointed by the 'p'  in do_composition()
1223 		 * again to do composition with the next non-Starter.  in do_composition()
1228 		 * If there was a match and a composition done and we have  in do_composition()
1229 		 * more to check on, then, we retrieve a new composition final  in do_composition()
1231 		 * composition again.  in do_composition()
1264 		 * There is no more composition possible.  in do_composition()
1266 		 * If there was no composition what so ever then we copy  in do_composition()
1289 	 * we do so and we do so until there is no more of composition  in do_composition()
1365 	 * Since composition always reduces the number of characters or  in do_composition()
1484 	 * an optional canonical composition. Please be noted that  in collect_a_seq()
1485 	 * canonical composition is done only when a decomposition is  in collect_a_seq()
1717 		 * Now do the canonical composition. Note that we do this  in collect_a_seq()
