Eg, before with a .gitattributes like: *.2 annex.numcopies=2 *.1 annex.numcopies=1 And foo.1 and foo.2 having the same content and key, git-annex drop foo.1 foo.2 would succeed, leaving just 1 copy, despite foo.2 needing 2 copies. It dropped foo.1 first and then skipped foo.2 since its content was gone. Now that the keys database includes locked files, this longstanding wart can be fixed. Sponsored-by: Noam Kremen on Patreon
