+    strmake(dst,src,length) moves length characters, or until end, of src to
+    dst and appends a closing NUL to dst.
+    Note that if strlen(src) >= length then dst[length] will be set to \0
+    strmake() returns pointer to closing null

+    'length' is the maximum length of the string; the buffer needs
+    to be one character larger to accomodate the terminating '\0'.
+    This is easy to get wrong, so we make sure we write to the
+    entire length of the buffer to identify incorrect buffer-sizes.
+    We only initialise the "unused" part of the buffer here, a) for
+    efficiency, and b) because dst==src is allowed, so initialising
+    the entire buffer would overwrite the source-string. Also, we
+    write a character rather than '\0' as this makes spotting these
+    problems in the results easier.
