patchbomb: add a 'patchbomb.intro' option This option allows the user to control the default behavior for including an introduction message. This avoids having to tirelessly skip the intro for people contributing to Mercurial. The three possibles values are: - always, - auto (default, current behavior), - never. I was thinking of ("true", "false", "") (empty value being auto) but I ruled it out as too confusing. This new config option reuses the pre-existing 'patchbomb' section.

patchbomb: extract 'getoutgoing' closure into its own function This continues my crusade against closure complication.

perf: add a perfloadmarkers command It is used to benchmark the obsstore initialization time.

rebase: move base calculation from rebasenode() to defineparents() We want to collect all calculation in one place.

largefiles: remove redundant checks for false modify/delete conflicts In a34a99181f36 (largefiles: don't show largefile/normal prompts if one side is unchanged, 2014-12-01), overridecalculateupdates() started checking for false modify/delete conflicts in large files and their standins. Then, in the very next changeset, 902554884335 (merge: before cd/dc prompt, check that changed side really changed, 2014-12-01), calculateupdates() itself started checking for false modify/delete conflicts in all files. Since "large files and their standins" is a subset of "all files", we can now drop the checks in overridecalculateupdates().

merge: make 'keep' message more descriptive Most merge action messages don't describe the action itself, they describe the reason the action was taken. The only exeption is the 'k' action, for which the message is just "keep" and instead there is a code comment folling it that says "remote unchanged". Let's move that comment into the merge action message.

addremove: restore the relative path printing when files are named This fixes the previously mentioned issue with 3778884197f0, and undoes its corresponding test change. The test change demonstrates the correctness when a file is specified (i.e. the glob is required on Windows because relative paths use '\' and absolute paths use '/'). It is admittedly very subtle, but there will be a more robust test in the addremove -S v3 series.

match: introduce uipath() to properly style a file path Several methods print files relative to the repo root, unless files are named on the command line, in which case they are printed relative to cwd. Since the check relies on the 'pats' parameter, which needs to be replaced by a matcher when adding subrepo support, this logic gets folded into the matcher to tidy up the callers. Prior to 3778884197f0, this style decision was based off of whether or not the 'pats' list was empty. That change altered the check to test match.anypats() instead, in order to make paths printed consistent when -I/-X is specified. That however, changed the style when a file is given to the command. So now we test the pattern list to get the old behavior for files, as well as test -I/-X to get the consistency for patterns.

update: don't overwrite untracked ignored files on update When looking for untracked files that would conflict with a tracked file in the target revision (or the remote side of a merge), we explcitly exclude ignored files. The code was added in 7e30f5f2285f (merge: refactor unknown file conflict checking, 2012-02-09), but it seems like only unknown, not ignored, files were considered since the beginning of time. Although ignored files are mostly build outputs and backup files, we should still not overwrite them. Fix by simply removing the explicit check.
