Hello!
I'm having a problem exemplified by the following code snippet: (lets
call this prblm.vim)
au BufEnter * sil! call Prblm(expand("<amatch>"))
fun! Prblm(fname)
let g:junk= 1
echomsg "TESTING<".a:fname.">"
endfun
vsplit
Use vim -u NONE prblm.vim
:so %
:echo g:junk
At this point, we get E121 and E15. Expected.
:mess
No messages other than the error messages from before.
:enew
:echo g:junk
Note that g:junk is now equal to 1. OK so far...
:mess
The "TESTING..." message is missing, but since g:junk both exists and is
equal to 1, obviously the Prblm() function was called. (scientific linux
6.3; vim 7.4.25, huge).

From a cscope "text" search of the Vim source:
E121: Undefined variable: %s
E15: Invalid expression: %s
These were for g:junk (undefined at the time of your first :echo
command) weren't they?
I don't… Oh, wait! From ":help :silent":
"Normal messages will not be given or added to the message history. When
[!] is added, error messages will also be skipped, and commands and
mappings will not be aborted when an error is detected. |v:errmsg| is
still set. When [!] is not used, an error message will cause further
messages to be displayed normally."
:echomsg displays a "normal" message and adds it to command history… but
that message is suppressed because of your ":silent" command.
Best regards,
Tony.
