extdiff: expand tildes and variables in paths to user-supplied diff programs

setup.py: do not install c extensions on pypy These extensions are slower on pypy because pypy has a JIT compiler. And also, they often do not compile (it depends on the pypy configuration).

copyright: update to 2015 Many files and translations have an outdated copyright date. Change that to the correct "2005-2015" dates.

changegroup: emit full-replacement deltas if either revision is censored To ensure that exchanged deltas in the presence of censored revisions can always be applied to the recipient repository, the deltas must replace the entire base text. To make this restriction reasonably enforceable, the delta must do so with a single patch operation. For background and broader design of the censorship feature, see: http://mercurial.selenic.com/wiki/CensorPlan

log: make -fr show complete history from the given revs Right now it's very obtuse to show the history of a particular rev (hg log -r 'reverse(::foo)'). This changes the -f option to make it follow history for the revs specified by -r. The current -f -r behavior is to limit the result of -r to only the commits that are ancestors of the current working copy. Changing this is a bit of a BC break, but the old behavior is A) rare, B) easy to emulate (& ::.), and C) currently undefined. The new behavior is frequently requested enough that I think the change is worth it.

util: accept "now, today, yesterday" for dates even the locale is not english Hi there! Fixed date names are helpful for automated systems. So it is possible to use english date parameter even if the underlying system uses another locale. We have here a jenkins with build jobs on different slaves that will do some operations with "dates" parameter. Some systems uses English locale and some systems uses German locale. So we needed to configure the job to uses other date names. As this is really annoying to keep the systems locale in mind for some operations I looked into util.py. It would be helpful for automated systems if the "default English" date names would even usable on other locales. I attached a simple patch for this. Best regards André Klitzing

copies: only calculate 'addedinm[12]' sets once Pass the addedinm1 and addedinm2 instead of m1, m2, ma into _computenonoverlap() instead of calculating the sets twice.

copies: calculate 'bothnew' from manifestdict.filesnotin() In the same spirit as the previous change, let's now calculate the 'bothnew' variable using manifestdict.filesnotin().5D

copies: replace _nonoverlap() by calls to manifestdict.filesnotin() Now that we have manifestdict.filesnotin(), we can write _nonoverlap() in terms of that method instead, enabling future speedups when filesnotin() gets optimized, and perhaps making the code a little clearer at the same time.

copies: move code into new manifestdict.filesnotin() method copies._computeforwardmissing() finds files in one context that is not in the other. Let's move this code into a new method on manifestdict, so m1.filesnotin(m2) can be optimized for various types of manifests (we expect more types of manifests soon).
