your constructed file name "[ScratchNNN]" is also a valid wildcard. If a
file named 'S' or 'c' or 'a' or so on, Vim will load this file into a
buffer.

My guess is that while the scratchbuf_no increases there will be both a
one-letter file name and a one-digit file name that Vim wants to load or
two one-digit file names. But because you use ":edit" to create the
scratch buffer and ":edit" only allows one single file name you get the
E77 error message.

If it happens again execute ":echo g:scratchbuf_no" and check what files
exist in your current directory.

Jürgen
