shelve: adds restoring newly created branch (issue5048) (BC) Before this patch shelve never preserved branch information, so after applying unshelve branch was the same as it was on working copy no matter in which branch shelve took place. This patch makes bare shelving(with no files specified, without interactive,include and exclude option) remembers information if the working directory was on newly created branch ,in other words working directory was on different branch than its first parent. In this situation unshelving restores branch information to the working directory.

shelve: make non bare shelve not saving branch information in bundle This patch prepares for restoring newly created branch only on bare shelve later because information about new-branch will be preserved only when shelve was bare and working copy branch was different than branch of its parent. In other case information about new-branch will be gone, so unshelve will not recognise that shelve was made on new-branch and it will not restore branch information from the bundle to the working directory.

shelve: preserve newly created branch on non-bare shelve in wctx (BC) Before this patch current branch in working context wasnt preserved after shelve, this patch makes it restore after update.

crecord: rewrite a comment about filtering patches I couldn't parse the previous version. I think the rewrite better expresses the intent of that comment.

run-tests: teach _processoutput to handle multiple lines of churn Instead of treating expected output as happening in a precise order, and assuming that if a line is missing it will never happen, assume that expected output is a prioritized list of likely matching lines. This means that if: foo/bar (glob) baz/bad (glob) changes to: baz/bad foo/bar instead of generating: baz/bad foo/bar For which we've lost both (glob) markers, we will match both lines and generate: baz/bad (glob) foo/bar (glob) This retains any special annotations we have for lines.

run-tests: indent _processoutput to aid readability for next patch The next commit will loop over the expected[pos] list, this change makes that change easier to review.

namespaces: fix name/node confusion There was a lot of copy/paste here.

tests: add test for "log -r wdir() -p" (issue4871) The issue has been fixed by 93bcc73df8d5, "cmdutil.changeset_printer: pass context into showpatch()". This patch adds test to prevent future regression.

tests: include modified/added/removed files in "log -r wdir()" output This patch prepares for the test of "hg log -r wdir() -p".
