hg import: better file accounting -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hg import: better file accounting From: Chris Mason <mason@suse.com> Change hg import to call hg addremove with the file list to make sure files added/deleted by the patch are properly accounted for. Instead of using lsdiff, the output of patch is parsed directly to find the file list. manifest hash: defed8cb90d6f976fb47949ac03dc4b88870ba77 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCsG1BywK+sNU5EO8RAvV9AJ9H25L5vdnZB1xpAakuN3tGuMfRfgCfdAgP 3xBc3S4F74/7DdS2GXRNhGw= =oXXT -----END PGP SIGNATURE-----
