Subject: cvsserver: Allow to "add" a removed file
X-Git-Tag: v1.5.2-rc0~34^2~3
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=4db0c8dec5c009cbbb61135a321a48278e668a25;p=git.git

cvsserver: Allow to "add" a removed file

CVS allows you to add a removed file (where the
removal is not yet committed) which will
cause the server to send the latest revision of the
file and to delete the "removed" status.

Copy this behaviour.
