Cannot process scripts beyond an embedded NULL character when running in 'source' mode

[Roman Rakus]

When you are sourcing bash script, which contains \0 character, bash 
thinks it is end of file.
I have investigated, that `source' loads entire file into memory as 
string. Then \0 is end of this string.
One of the possible solution is to left out all \0 characters. This 
doesn't seem to be perfect.
Another possible solution is to count size of the file and then compare 
the size with actual string parsing.
Maybe other solutions...

Which solution should be the best?
