qdiff: migrate to modern pager API This results in the default pager-attend list being empty. Sadly, we can't let the code be that way, because some legacy extensions depend on hooking the pager's attend list at import time (and we'd like to not break them), and if the list is actually *empty* that triggers magic behavior in the extension that attends everything. Instead, we put a long, improbable command name as the only entry in the attend list.

annotate: start pager after we're sure we wont abort This avoids needlessly putting a short error message into the pager.

dispatch: consolidate pager flag handling to a single place This makes a little more sense, thanks to Martin for suggesting it.

ui: rename neverpager to disablepager I agree this is a clearer name for this method.

scmutil: proxy revrange() through repo to break import cycles This was one of the hardest import cycles as scmutil is widely used and revset functions are likely to depend on a variety of modules. New repo.anyrevs() does not expand user aliases by default to copy the behavior of the existing repo.revs(). I don't want to add new function to localrepository, but this function is quite similar to repo.revs() so it won't increase the complexity of the localrepository class so much.

revset: split language services to revsetlang module (API) New revsetlang module hosts parser, tokenizer, and miscellaneous functions working on parsed tree. It does not include functions for evaluation such as getset() and match(). 2288 mercurial/revset.py 684 mercurial/revsetlang.py 2972 total get*() functions are aliased since they are common in revset.py.
