[nail-devel] folder hooks and "sourcing"

[Stephen I. <3s9...@sn...>]

The nail man page says, "As a special case, you can  type  a newline as your
first command to nail to type the first message".  I've recently discovered
that this does not remain true if you have a folder hook command that flags
some of the messages in your inbox before you start your session.  Looking at
the source code, I think the reason is that the hook causes the "sawcom"
variable to be set, which in turn affects the action of the "next" command,
which gets executed when you type a newline as your command.  Again from my
reading of the source code, it appears that the hook wouldn't have this effect
if it were run with the variable "sourcing" set to true, as it is when
commands from .mailrc are being executed.  Wouldn't it be appropriate to set
"sourcing" true for folder hooks on general principles?  The commands executed
by the hook are not really interactive, and have a status more like ones in
.mailrc than like commands you type at your terminal once the session is
started.
