I've got a fix for those of you out there that might have source to modify.
The fix is in the file ex_vget.c, in the getbr() function.  Basically, the
order in which the various strings are searched for input needs to be reordered.

If you take a look at the file, you'll notice it looks for input from
a few different buffers before going out to read something new.
The bug occurs because when the p command goes to read the characters
to "put", it ends up reading in the rest of the macro before the input
characters themselves.

This is the current order of the buffers searched:

        if (Peekkey) {  ...  }		/* Peek ahead buffer	*/
        if (vmacp) { ... }		/* Macro string buffer	*/
        if (Peek2key) { ... }		/* 2nd Peek ahead buffer*/
        if (vglobp) { ... }		/* New text to insert   */

The fix is to change the order like so:

        if (Peekkey) {  ...  }		/* Peek ahead buffer	*/
        if (Peek2key) { ... }		/* 2nd Peek ahead buffer*/
        if (vglobp) { ... }		/* New text to insert   */
        if (vmacp) { ... }		/* Macro string buffer	*/

This bug exists in V.3.2, and V.4 as well.
