Proposed tiny change for SQLite on IBM z/OS

With the IBM XL C compiler used to compile SQLite on IBM z/OS mainframe systems, the default C locale is supported by code page IBM-1047. 

In this code page the code point 0x15 is valid and represents the newline character. 

In its aiClass[] array, sqlite3.c marks code point 0x15 as invalid (0x28 - CC_ILLEGAL). This causes SQLite on z/OS to reject valid multi line SQL statements. 

I would like to propose the below tiny change, only affecting the EBCDIC implementation, which marks code point 0x15 as valid (CC_SPACE - 0x07) and fixes the problem. The diff is against v3.35.2.

Thanks for the report. This has been fixed on the trunk. There is likely to be a patch release soon incorporating this change.
