string.index_of_char is basically a wrapper around g_utf8_strchr. I
guess g_utf8_strchr could return null if c==0, but it does feel a bit
ridiculous. If you feel strongly about it you can file a bug against
glib.
Strings in Vala (and C) can't really contain NUL since NUL is used to
mark the end of a string, and it isn't typically considered to be part
of the string (i.e., strlen() doesn't include it). To put it another
way, string.index_of_char('\x00') is basically asking, "What is the
index of the first occurrence of NUL before the first occurrence of
NUL?".

Nope, that's basically right.
