template: add showbranch template for {branch} Like showbranches, but always yields exactly one branch. Replaces the less correct {branches|nonempty}.

subrepo: avoids empty commit when .hgsubstate is dirty (issue2403) This patch avoids empty commit when .hgsubstate is dirty. Empty commit was caused by .hgsubstate being updated back to the state of the working copy parent when committing, if a user had changed it manually and not made any changes in subrepositories. The subrepository state from the working copies parent is compared with the state calculated as a result of trying to commit the subrepositories. If the two states are the same, then return None otherwise the commit is just done. The line: "committing subrepository x" will be written if there is nothing committed, but .hgsubstate is dirty for x subrepository.

progress: don't compute estimate without a total Without this, computing an estimate crashes. Test included.

subrepo: use low-level git-diff-index for dirty() Despite its name, git-diff-index compares a revision to the files in the working directory. This seems way less sketchy and more future proof than parsing human-readable git-status.

subrepo: defer determination of git's current branch

subrepo: incorporate tracking branches into gitbranchmap

subrepo: use low-level git-for-each-ref command in branchmap This command's output doesn't change across versions, and it also disambiguates cases where there are slashes in local branch names.

progress using tests: disable time estimates to avoid flakiness

progress: include time estimate as part of the default progress format

progress: only show time estimate when progress format contains 'estimate'
