patch.difffeatureopts: add a feature for whitespace diffopts These aren't exactly format-breaking features -- just ones for which patches applied to a repo will produce incorrect commits, In any case, some commands like record and annotate only care about this feature.

patch.difffeatureopts: add a feature for diff.git This deserves to be its own feature -- indeed, this is often the only feature several commands care about.

patch: rename diffopts to diffallopts This is meant to be used when all features are explicitly requested. diffopts is kept as an alias for now -- it will go away soon.

patch: add a new function to initialize diffopts by feature Not all callers are interested in all diffopts -- for example, commands like record (which use diff internally) break when diffopts like noprefix are enabled. This function will allow us to add flags that callers can use to enable only the features they're interested in.

patch.diffopts: use a dict for initialization In upcoming patches we'll conditionally add to and remove from the dict.

largefiles: split the creation of a normal matcher out of its install method Refactoring addremove to support subrepos will need the ability to keep passing the same matcher and narrowing it, instead of monkey patching scmutil's matcher.

addremove: print relative paths when called with -I/-X (BC) For "hg addremove 'glob:*.py'", we print any paths added or removed as relative to the current directory, but when "hg addremove -I 'glob:*.py'" is used, we use the absolute path (relative from the repo root). It seems like they should be the same, so change it so we use relative paths in both cases. Continue to use absolute paths when no patterns are given.
