-**
-**  Concatenate strings with dynamic memory allocation.
-**
-**  Written by Russ Allbery <rra@stanford.edu>
-**  This work is hereby placed in the public domain by its author.
-**
-**  Usage:
-** 
-**       string = concat(string1, string2, ..., (char *) 0);
-**       path = concatpath(base, name);
-**
-**  Dynamically allocates (using xmalloc) sufficient memory to hold all of
-**  the strings given and then concatenates them together into that
-**  allocated memory, returning a pointer to it.  Caller is responsible for
-**  freeing.  Assumes xmalloc is available.  The last argument must be a
-**  null pointer (to a char *, if you actually find a platform where it
-**  matters).
-**
-**  concatpath is similar, except that it only takes two arguments.  If the
-**  second argument begins with / or ./, a copy of it is returned;
-**  otherwise, the first argument, a slash, and the second argument are
-**  concatenated together and returned.  This is useful for building file
-**  names where names that aren't fully qualified are qualified with some
-**  particular directory.
