Possible oveflow

[Bbulatov]

Hello!
During the static analysis was detected possible overflow. Accessing an element of array 'file->unget_data' of size 1000 (cron.h:219) at misc.c:94 can lead to a buffer overflow, since the index 'buffer->unget_count' can have an out of range value between 1001 and 1023, as indicated by a preceding conditional expression at misc.c:88 (>=1024). Please clarify whether this is critical?
