vcs-svn: let deltas use data from postimage
The copyfrom_target instruction copies appends data that is already present in the current output view to the end of output. (The offset argument is relative to the beginning of output produced in the current window.) The region copied is allowed to run past the end of the existing output. To support that case, copy one character at a time rather than calling memcpy or memmove. This allows copyfrom_target to be used once to repeat a string many times. For example: COPYFROM_DATA 2 COPYFROM_OUTPUT 10, 0 DATA "ab" would produce the output "ababababababababababab".
