Does not check for buffer overflows when concatenating to destination
[MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
snprintf (warning: strncat is easily misused). Risk is low because the
source is a constant character.

Does not handle strings that are not \0-terminated; if given one it may
perform an over-read (it could cause a crash if unprotected) (CWE-126).
