-/* This function is used when building up strings of unknown length. Room is
-always left for a terminating zero to be added to the string that is being
-built. This function does not require the string that is being added to be NUL
-terminated, because the number of characters to add is given explicitly. It is
-sometimes called to extract parts of other strings.
-
-Arguments:
- string points to the start of the string that is being built, or NULL
- if this is a new string that has no contents yet
- s points to characters to add
- count count of characters to add; must not exceed the length of s, if s
- is a C string.
-
-Returns: pointer to the start of the string, changed if copied for expansion.
- Note that a NUL is not added, though space is left for one. This is
- because string_cat() is often called multiple times to build up a
- string - there's no point adding the NUL till the end.
