upgrade: import 'localrepo' globally The in-function imports mention a cycle that seems to no longer be relevant. As a result, we just import it globally.

largefiles: set the extension as enabled locally after a share requiring it This has been done for clone since e1dbe0b215ae, so it makes sense here for the same reasons.

windows: add context manager support to mixedfilemodewrapper I stumbled into this in the next patch. The difference between getting a context manager capable object or not from vfs classes was as subtle as adding a '+' to the file mode.

chg: always wait for pager Previously, when runcommand raises, chg aborts with, and does not wait for pager. The call stack is like: hgc_runcommand -> handleresponse -> readchannel -> debugmsg("failed to read channel") -> exit(255) That means, chg returns to the shell, then both the pager and the shell will read from the terminal at the same time, causing problems. This patch fixes that by using "atexit" to register the pager cleanup function so chg will always wait for pager even if runcommand raises.

bundle2: move 'seek' and 'tell' methods off the unpackermixin class These methods are unrelated to unpacking. They are used internally by the 'unbundlepart' class only. So me move them there as private methods. In the same go, we clarify their internal role in the their docstring.

shelve: rename nodestoprune to nodestoremove As per feedback from the community.

templater: port pad() to take keyword arguments This is another example where keyword arguments can be actually useful.

templater: add support for keyword arguments Unlike revset, function arguments are pre-processed in templater. That's why we need to define argspec per function. An argspec field looks somewhat redundant in @templatefunc definition as a name field contains human-readable list of arguments. I'll make function doc be built from argspec later. Ported separate() function as an example.

templater: add parsing rule for key-value pair Based on the revset implementation, 70a2082f855a. This patch also adjusts the test as '=' is now a valid token.

templater: adjust binding strengths to make room for key-value operator Changed as follows: - template ops (%, |): +10 - arithmetic ops: +1 (but "negate" should be greater than "%")
