bash_completion: add -p|--patch|--stat support for shelve

test-convert-git: silence commit output for stablity When running the tests with 1.7.7.6, I get 'files' and 'insertions' instead of the singular forms, and there is also an additional '0 deletions(-)' at the end. Since this doesn't seem important to the test, silence it.

rebase: preserve the 'intermediate-source' attribute of grafts Preserving the 'source' attribute of grafts started with a69a77a80900, which predates the introduction of 'intermediate-source' in 51930a7180bd by a year and a half. It looks like not preserving this was an oversight. On a related note, notice how the source value of 32af76 is no longer visible in the graph above this test. Is it reasonable to import the sha1 translation from evolve.py:relocate() into scmutil or similar, and use that to fixup these attributes as well as the commit message? (I realize that evolve is still experimental, but I don't see a way to do this from the evolve extension.)

merge with stable

verify: add a hook that can let extensions manipulate file lists Without a hook of this nature, narrowhg[0] clones always result in 'hg verify' reporting terrible damage to the entire repository history. With this hook, we can ignore files that aren't supposed to be in the clone, and then get an accurate report of any damage present (or not) in the repo. 0: https://bitbucket.org/Google/narrowhg

resolve: don't abort when file is missing A file being missing is a completely valid situation in which the user may want to re-resolve merge conflicts. Mercurial already maintains backups of local data, so this turns out to be easy to handle.

filemerge: treat EOF at prompt as fail, not abort Previously we'd abort the merge entirely if there was an EOF at the prompt. This is unnecessary -- it's much better to simply fail and treat the file as unresolved instead.

test-merge-tools.t: add 'hg resolve --list' output to tests In upcoming patches we're going to be making some improvements to the ':prompt' merge tool, and one of them is recovering appropriately from exceptions. It is important in such cases to make sure that the merge state is written out properly. I went through the output and verified that it all makes sense.

error: add structured exception for EOF at prompt We'll catch this exception for promptchoice queries to provide better error handling.

test-merge-prompt.t: unset HGMERGE We're going to test behavior with and without HGMERGE, so disable it for the test.
