That could be done with "conditional comments" like

# if <some-condition> then
[core]
        pager = less
# endif

That's rather ugly, and the implementation would be even more ugly, but
backward-compatible.

Same here, with push.default = upstream, which breaks old versions of
Git ;-).

(I have a recent Git on my desktop, and my $HOME is shared with a server
running Debian oldstable)
