resolve: keep wlock while resolving This will make resolve use correct locking and thus make it more safe. Resolve is usually a long running command spending a lot of time waiting for user input on hard problems. It is thus a real world scenario to start multiple resolves at once or run other commands (such as up -C and merge) while resolve is running. Proper locking prevents that.

keyword: suppress keyword expansion while 'hg fetch' for internal merge Before this patch, 'hg fetch' may cause unexpected conflict, if 'hg fetch'-ed changes are located near lines in which keywords are embedded, because keywords are substituted with other strings in the working directory. This patch suppresses keyword expansion while 'hg fetch' for internal merge by adding 'fetch' to 'restricted' command list like 'merge'. This patch uses 'hg import' to safely create the new head to be merged at succeeding 'hg fetch', because: - branch of revision #10 is different from one of #11 in 'Test' repository, so just 'hg fetch -r 11' doesn't cause merging between them this means the new head should be created manually. - 'hg import' is easier and safer than 'cat <<EOF' and 'hg commit' to replay same changes including special characters like '$' safeness of 'hg import' with keyword extension is already examined in 'test-keyword.t'.

keyword: suppress keyword expansion while 'hg histedit' for internal merge Before this patch, 'hg histedit' may cause unexpected conflict, if 'hg histedit'-ed changes are located near lines in which keywords are embedded, because keywords are substituted with other strings in the working directory. This patch suppresses keyword expansion while 'hg histedit' for internal merge by adding 'histedit' to 'restricted' command list like 'merge'. Test in this patch just swaps order of revision #13 and #14: this is enough to cause internal merge.
