You are right in that Exim works with C-style strings that cannot
contain NUL characters, and so Nico is right in that strictly the
functions should therefore be called "strsomething". The reason there is
a length parameter on the string_cat() function is so that it can be
used to pick out substrings.
Hmm. I'm not sure what I think about the patch. You are probably right
about the efficiency, and for that reason it is perhaps a good idea
anyway. I'll think about it.
