Arbitraryfilectx.cmp does not follow symlinks:
$ mkdir case1
$ cd case1
$ hg init
#if symlink
$ printf "A" > real_A
$ printf "foo" > A
$ printf "foo" > B
$ ln -s A sym_A
$ hg add .
adding A
adding B
adding real_A
adding sym_A

These files are different and should return True (different):
(Note that filecmp.cmp's return semantics are inverted from ours, so we invert
for simplicity):
$ hg eval "context.arbitraryfilectx('A', repo).cmp(repo[None]['real_A'])"
True (no-eol)
$ hg eval "not filecmp.cmp('A', 'real_A')"
True (no-eol)
These files are identical and should return False (same):
$ hg eval "context.arbitraryfilectx('A', repo).cmp(repo[None]['A'])"
False (no-eol)
$ hg eval "context.arbitraryfilectx('A', repo).cmp(repo[None]['B'])"
False (no-eol)
$ hg eval "not filecmp.cmp('A', 'B')"
False (no-eol)
This comparison should also return False, since A and sym_A are substantially
the same in the eyes of ``filectx.cmp``, which looks at data only.
$ hg eval "context.arbitraryfilectx('real_A', repo).cmp(repo[None]['sym_A'])"
False (no-eol)
A naive use of filecmp on those two would wrongly return True, since it follows
the symlink to "A", which has different contents.
#if symlink
$ hg eval "not filecmp.cmp('real_A', 'sym_A')"
True (no-eol)
#else
$ hg eval "not filecmp.cmp('real_A', 'sym_A')"
False (no-eol)
#endif
