internals: document revlog format
It seems like a good idea to document the revlog format.
There is a lot more that could be added to this documentation.
But you have to start somewhere.
fixbundle() {
grep -v 'saving bundle' | grep -v 'saved backup' | \
grep -v added | grep -v adding | \
grep -v "unable to find 'e' for patching" | \
grep -v "e: No such file or directory" | \
cat
}
