Auto packing your repository for optimum performance. You may also
run "git gc" manually. See "git help gc" for more information.

IMO there is a broken hueristic in there somewhere... I regularly run 'git gc' on my repos...


Follow-up...   this is already becoming a PITA.

I am going through and rebasing multiple repos in the same repository... and it keeps running 'git gc' on each branch! grrrr.

Step 1:
pull "../linux-2.6" into master branch of local repo. this repo was created with "--reference". It _might_ be reasonable to expect 'git gc' to be run:

[jgarzik@pretzel libata-dev]$ git pull ../linux-2.6/

Step 2:
In the same repo, rebase a branch (contains a single changeset), immediately following step #1:

[jgarzik@pretzel libata-dev]$ git branch
  ALL
  NEXT
* master
  mv-ahci-pata
  new-eh
  sii-lbt
[jgarzik@pretzel libata-dev]$ git-checkout sii-lbt && git-rebase master
Switched to branch "sii-lbt"
First, rewinding head to replay your work on top of it...
HEAD is now at 7704a8b... Merge branch 'for-linus' of git://oss.sgi.com:8090/xfs/xfs-2.6

Step 3:
Ditto, a second rebase in the same repo, immediately following step #2:

[jgarzik@pretzel libata-dev]$ git-checkout new-eh && git-rebase master
Switched to branch "new-eh"
First, rewinding head to replay your work on top of it...
HEAD is now at 7704a8b... Merge branch 'for-linus' of git://oss.sgi.com:8090/xfs/xfs-2.6

Step 4:

[jgarzik@pretzel libata-dev]$ git-checkout mv-ahci-pata && git-rebase master
Switched to branch "mv-ahci-pata"

Will the 'git gc' never end???
