Description:
A typo in the is_in_incremental function in innobackup.c may cause an iteratation to go beyond the end of an array. When this happens mysqlbackup seems to crash without warning and without returning an exit code. If a full backup is taken and a table is deleted before an incremental backup is taken it will not be possible to run apply-log of the incremental backup towards the full backup.

How to repeat:
Please read the source code of mysqlbackup for the is_in_incremental function

Thanks victor for debugging the crash and for the suggested patch.

Code patch and modification of incremental test cases are fine.
