The generation of cache files like tags.cache and branchheads.cache is not an actual reflection of things changing in the whole of the .hg directory (like eg a commit or a rebase or something) but instead these cache files are just part of bookkeeping. As such its convienant to allow various clients to ignore file events to do with these cache files which would otherwise cause a double refresh. Eg one refresh might occur after a commit, but the act of refreshing after the commit would cause Mercurial to generate a new branchheads.cache which would then cause a second refresh, for clients. However if these cache files are moved into a directory like eg .hg/cache/ then GUI clients on OSX (and possibly other platforms) can happily ignore file events in this cache directory.

Test that we don't lose the setgid bit when we call chmod.

Not all systems support setgid directories (e.g. HFS+), so
|
|
just check that directories have the same mode.
