Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Enhancement request. Provide an easy way to specify a predicate that
inhibits (or activates) auto-revert for a given buffer.
See this question, for example:
http://emacs.stackexchange.com/q/29591/105
I provided this answer, but it might be helpful if Emacs provided a
variable whose value is a predicate that determines whether the current
buffer can be auto-reverted. Emacs provides a variable,
`global-auto-revert-ignore-buffer', to test for auto-reversion. In
addition or instead, it could provide a predicate-valued variable.
Simpler, perhaps, is to let the value of
`global-auto-revert-ignore-buffer' be, alternatively, a predicate, which
is called when the buffer is set up (e.g. `after-file-hook', for a file
buffer). The return value would be handled just like the current value
of `global-auto-revert-ignore-buffer' is handled now.

I think that makes sense. What parameter(s) would the predicate take?
The buffer or the file name... or both? Hm... Looking at the code
where `global-auto-revert-ignore-buffer' is consulted, we're in the
correct buffer, but it may not have a file name, so I guess the buffer
should be the parameter?

I've now made this change on the trunk.
