    [git-rebase-update] Disallow `git gc` during git-rebase-update. · d3acb16c
    Robert Iannucci authored
    In theory this should prevent `git rebase-update` from invoking
    potentially expensive `git gc` operations after every `git rebase`
    (ideally once per branch, but sometimes as many as three per branch (!)).
    
    This has outsized effects as the size of the repo or number of branches
    increases, and additionally has penalties on Windows due to git's
    POSIXey assumptions around how disk I/O works.
    
    After doing all rebase stuff, we run `git gc --auto` from rebase-update
    once (assuming we were successful; if the command failed then we don't
    run gc at all).
