localrepo.clone: add a way to override server preferuncompressed Without this patch, if the server sets preferuncompressed, there's no way for clients to override that and force a non-streaming clone. With this patch, we extend the meaning of --pull to also override preferuncompressed and force a non-streaming clone.

hg.clone: set 'stream' depending on whether --pull was requested or not In an upcoming patch we'll differentiate between the two in localrepo.

merge: perform case-collision checking on final set of actions When there are multiple common ancestors, we should check for case collisions only on the resulting actions after bid merge has run. To do this, move the code until after bid merge. Move it past _resolvetrivial() too, since that might update actions. If the remote changed a file and then reverted the change, while the local side deleted the file and created a new file with a name that case-folds like the old file, we should fail before this patch but not after. Although the changes to the actions caused by _forgetremoved() should have no effect on case collisions, move it after that, too, so the next person reading the code won't have to think about it. Moving it past these blocks of code takes it to the end of calculateupdates(), so let's even move it outside of the method, so we also check collisions in actions produced by extensions overriding the method.

spelling: fixes from proofreading of spell checker issues

tests: allow more flexibility in git diffstat output The output of 'git diff --stat' changed in git 1.7.10 and 1.7.11. To ensure the tests work with earlier versions of git as well, the output is now wrapped with a whitespace regex.

merge: move cd/dc prompts after largefiles prompts By moving the cd/dc prompts out of calculateupdates(), we let largefiles' overridecalculateupdates() so the unresolved values (i.e. 'cd' or 'dc' rather than 'g', 'r', 'a' and missing). This allows overridecalculateupdates() to ask the user whether to keep the normal file or the largefile before the user gets the cd/dc prompt. Whichever answer the user gives, we make overridecalculateupdates() replace 'cd' or 'dc' action, saving the user one annoying (and less clear) question.

addremove: automatically process a subrepository's subrepos Since addremove on the top of a directory tree will recursively handle sub directories, it should be the same with deep subrepos, once the user has explicitly asked to process a subrepo. This really only has an effect when a path that is a subrepo (or is in a subrepo) is given, since -S causes all subrepos to be processed already. An addremove without a path that crosses into a subrepo, will still not enter any subrepos, per backward compatibility rules.

addremove: support addremove with explicit paths in subrepos Git and svn subrepos are currently not supported.

addremove: add support for the -S flag Git and svn subrepos are currently not supported. It doesn't look like git or svn have these commands natively, so that's an area for a git or svn expert.

commit: propagate --addremove to subrepos if -S is specified (issue3759) The recursive addremove operation occurs completely before the first subrepo is committed. Only hg subrepos support the addremove operation at the moment- svn and git subrepos will warn and abort the commit.
