Hi, Leo.
Thanks for the suggestion.
It's my understanding that the convention for hooks to receive no
arguments and for more complicated functions to be used only when
necessary.
From the Emacs info page 48.2.2
Most hooks are "normal hooks". This means that when Emacs runs the
hook, it calls each hook function in turn, with no arguments. We
have made an effort to keep most hooks normal, so that you can use
them in a uniform way. Every variable whose name ends in `-hook' is
a normal hook.
A few hooks are "abnormal hooks". Their names end in `-functions',
instead of `-hook' (some old code may also use the deprecated suffix
`-hooks'). What makes these hooks abnormal is the way its functions
are called--perhaps they are given arguments, or perhaps the values
they return are used in some way. For example,
`find-file-not-found-functions' is abnormal because as soon as one
hook function returns a non-`nil' value, the rest are not called at
all (*note Visiting::). The documentation of each abnormal hook
variable explains how its functions are used.
I'd like to keep things as simple as possible. I think two normal hooks
are simpler than one abnormal hook.
Brian
