fix the dummy 00changelog.i not being copied on clone

Make test-convert-git compatible with other git versions (tested with 1.4.4.3)

When reverting a file which was renamed, also revert the old name

correctly record file-level history when the local side renames a directory

Fix theoretical issue in filecommit. If the file was copied, we don't want to reuse the original entry. I think this is mostly a theoretical issue - when there are copies, fp1 == nullid, so it's very unlikely that the fl.cmp(fp1, t) would think the file was unmodified. In any case, if there was a copy, we should forcefully create a new entry.

Avoid adding to the changelog executable files added by the second parent. This was a regression introduced by b51a8138292a.

avoid double slash problem mentioned in issue695

clone: remove "file://" before making the path absolute This avoids writing bogus paths to .hgrc. Fixes issue695.

pull -u: if "url#rev" was given, update to rev

clone: if "url#rev" was given, update to rev

parseurl: also return the revision after the "#"; add a test

pull -r: pass the revisions as the heads argument of findincoming This can make a hg pull -r faster if the remote repo has many heads, and fixes an "abort: received changelog group is empty".

convert: fix /dev/null redirections under Windows

Test git repository conversion

hghave: detect git availability
