Ampersand in GECOS field buggette

Hi all,

[platform: FreeBSD 2.1.6, exim 1.61]

I had a brief problem, this morning, when I did a new exim
install, and suddenly, all mail from root came out as:

From: Charlie Exim configuration fileroot <root@???>

Which is not very good. :-) After a small bit of nosing
around, I found that changing the "strcat" to "strcpy" on line
1802 of exim.c fixes this entirely.

Have fun,
-Dom
