corrects memory consumpition for espacing non printable characters

Within the function string_printing2 in src/src/string.c, a non printable
character typically requires 4 bytes (backslash and three octal characters)
after escaping. However the function reserves 5 bytes for escaping a non
printable character (1 due to the length variable and 4 due to the
nonprintcount variable), as can be seen in line 305 of the relevant file.

The attached patch corrects the memory requirement from 5 to 4 bytes for the
escaping of non printable characters.
