That indeed is from long ago ;-) and I still kind of like it. Is
the issue that some platforms do not even have inum of the "thing"
connected to a file descriptor? I think a fallback code for such a
system can just return a constant pipe ID to anybody asks, so that
an exported GIT_PAGER_PIPE_ID would always match, which gives the
behaviour identical to what we currently do with GIT_PAGER_IN_USE,
and that would be one way to help those capable of giving useful IDs
while not harming others.
Thanks.
