fix: E495 on VimEnter with 'verbose'

[tomtomjhj]

Problem:
If 'verbose' is non-zero, VimEnter autocmd when starting vim without args raises E495:

Error detected while processing VimEnter Autocommands for "*"..function <SNR>37_UseConfigFiles:
line    6:
E495: No autocommand file name to substitute for "<afile>"

Solution:
Replace <afile> with #n (:help :_#n).

Thanks for the PR. I found the error shows up only if I start vim with no file. Perhaps the root cause of missing an <afile> is caused by the "No Name" buffer?

That's my understanding as well.
