move commands.addremove_lock to cmdutil.addremove

move walk and matchpats from commands to cmdutil.

fix patch.patch.filterfiles. now test-diff-subdir passes.

make test-diff-subdir executable.

tests: new test for hg diff of a subdirectory only

Make clear that hg pull -r REV pulls "up to" a revision. The existing message was a bit confusing, making the reader believe that only the specific revision is pulled.

Use cached hg-root-dir instead of rediscovering by a second call to (hg-root). We have the path we need already as the value of hg-root-dir.

hgweb: repo.changes() is now called repo.status()

remove localrepository.changes. use localrepository.status instead.

refactor text diff/patch code. rename commands.dodiff to patch.diff. rename commands.doexport to patch.export. move some functions from commands to new mercurial.cmdutil module. turn list of diff options into mdiff.diffopts class. patch.diff and patch.export now has clean api for call from 3rd party python code.

merge.

manifest.execf is now a function.

merge.

grep: add --follow support.

grep: display correct user/revision for --all in reverse. Also handle multiple occurrences of the same line by storing linestates in an array instead of a dict, and using difflib to compute the difference between linestates.

util: qualify name properly.

mq: demandload more

commands.import: refactor patch parsing into patch.extract.

merge git patch code.

Tests for git import

Remove debugging line

Fix bad merge with crew

Move patch-related code into its own module.

Teach import to understand git diff extensions. Vanilla patch chokes on git patches that include files that are copied or renamed, then modified. So this code detects that case and rewrites the patch if necessary.

update copyrights.

merge.

Fix some bugs introduced during the manifest refactoring

Fix "hg qnew -f foo" without -m The refresh method assumes it has a string.

merge with mpm.

Remove manifest.readflags
