i'll just put this here as a reminder to self for later...
f com -branch th1ish-R.I.P. --allow-empty -m "Moving th1ish out of trunk, as it's holding up a couple pending improvements in the core (and hasn't been hacked on in over 18 months other than to accommodations a few minor API changes). Its sloppy ref handling (by current standards) makes it untenable in conjunction with up-coming cwal improvements. th1ish is now dead. Long live th1ish (or not - s2 is far superior)." So now i'm curious... this is an empty commit, so in theory the only diff between the manifests needs to be the P, D, C, Z cards (i.e. no F-cards)... [odroid@host:~/fossil/cwal]$ f-acat th1ish-R.I.P.

When performing empty commits and using a delta manifest, we "could" elide all the F-cards, which implies also leaving out the R-card (or using the default hash for it). Granted, empty commits are rare (this might even be my first one ever), so this would be a micro-optimization, if at all. -- ----- stephan beal http://wanderinghorse.net/home/stephan/ http://gplus.to/sgbeal "Freedom is sloppy.
