color: add support for colorizing git subrepo diffs

tests: fix test-casefolding.t output This change started with a387b0390082.

synthrepo: new filenames must not also be new directories, and vice-versa When generating many new files into a set of many possible new directories, there is the possibility that the same path is chosen as both file and directory. How likely this is depends on the size of the dictionary used, the generated directory structure and the number of generated files.

status: don't override _buildstatus() in workingcommitctx Now that the caching into _status is done in workingctx._dirstatestatus(), which workingcommitctx._dirstatestatus() does not call, there is no caching to prevent in _buildstatus(), so stop overriding it.

status: cache dirstate status in _dirstatestatus() Since it's only the dirstate status we cache, it makes more sense to cache it in the _dirstatestatus() method. Note that this change means the dirstate status will also be cached when status is requested between the working copy and some other revision, while we currently only cache the result if exactly the status between the working copy and its parent is requested.

localrepo: add ignoremissing parameter to branchtip Previously, in the namespaces api, the only caller of branchtip was singlenode which happened to raise the same exception that branchtip raised: KeyError. This is a minor change but will allow upcoming patches to use repo.branchtip to not raise an exception if a branch doesn't exist. After that, it will be possible for extensions to use the namespace api in a stable way.

namespaces: add method to return a list of nodes for a given name This is a helpful method that some extensions can make use of (e.g. for custom revsets); currently not used in core.

namespaces: add test for log Now that we have enough features in the namespaces api, we add a test for it.

log: use new namespaces api to display names The only caveat here is that branches must be displayed first due to backwards compatibility. The order of namespaces is defined to be the 'update' order which, unfortunately, is not the same as log output order. It's worth mentioning that the log output is still translated the same as before since we are formating our strings the same way: # i18n: column positioning for "hg log" _("bookmark: %s\n") % bookmark becomes tname = _(("%s:" % ns.templatename).ljust(13) + "%s\n") % name when name == 'bookmark'. The ljust(13) keeps the strings and whitespace equal. Adding a new namespace is even easier now because the log output code doesn't need to change. A future programmer would just need to add the string to the corresponding .po file (which is the same as they would have had to do previously).

tests: add a i18n translation test for log output Upcoming patches will change the way that log output is generated so we add a test to ensure that the words 'branches', 'bookmarks', and 'tags' are still translated.

filectx: fix annotate to not directly instantiate filectx 28a302e9225d changed basefilectx.annotate() to directly instantiate new filectx's instead of going through self.filectx(), this breaks extensions that replace the filectx class, and would also break future uses that would need memfilectx's.

largefiles: don't print files as both large and normal in addremove dryruns

largefiles: return the list of added files from addlargefiles() This will be used to exclude largefile candidates from the normal file matcher, which will allow add and addremove dryruns to not print a file as both a normal and a large file.

largefiles: align the output messages for an added file with core methods Core addremove prints the file relative to cwd only if patterns are provided to the command. Core add always prints relative to cwd. Also, both methods print the subrepo prefix when needed. The 'already a largefile' doesn't have an analog in core, but follows the same rules for consistency.

largefiles: align the output messages for a removed file with core methods Both cmdutil.remove() and scmutil.addremove() require verbose mode or an inexact match to print the filename. Core addremove also prints the file relative to cwd only if patterns are provided to the command. And finally, both methods print the subrepo prefix when needed.

revset: use '%' as an operator for 'only' With this patch, we can make it much easier to specify 'only(A,B)' -> A%B. Similarly, 'only(A)' -> A%. On Windows, '%' is a semi-reserved symbol in the following way: using non-bash shells (e.g. cmd.exe but NOT PowerShell, ConEmu, and cmder), %var% is only expanded when 'var' exists and is surrounded by '%'. That only leaves batch scripts which could prove to be problematic. I posit that this isn't a big issue because any developer of batch scripts already knows that to use '%' one needs to escape it by using a double '%%'. Alternatives to '%' could be '=' but that might be limiting our future if we ever decide to use temporary assignments in a revset.
