export: invoke the file prefetch hook cmdutil.exportfile() is only called by shelve, mq and patchbomb. Those are unlikely to mix with lfs, but it may as well be invoked there for completeness.

scmutil: teach the file prefetch hook to handle multiple commits The remainder of the commands that need prefetch deal with multiple revisions. I initially coded this as a separate hook, but then it needed a list of files to handle `diff` and `grep`, so it didn't seem worth keeping them separate. Not every matcher will emit bad file messages (some are built from a list of files that are known to exist). But it seems better to filter this in one place than to push this on either each caller or each hook implementation.

tests: arrange for a server in wireproto-command-capabilities.t to be killed The stray servers were piling up after the test harness exited. On Windows, this means the *.pyd files can't be rebuilt, which is why the build warning count dropped to 1 recently.

revset: skip legacy lookup for revspec wrapped in 'revset(...)' Currently, multiple labels can take forms that can be confused with revset (eg: "rev(0)" is a valid tag). Since we look up for tags before evaluating revset, this means a tag can shadow a valid revset at any time. We now enforce the strict revset parsing when wrapped with 'revset(...)'. For now, This only work on a whole revspec (but can be used within the revset without effect). This might change in the future if we improve the implementation. The feature is undocumented for now, keeping it in the experimental namespace. In case a better approach to achieve the same goal is found. The syntax looks like a revset but is not implemented as such for now. Since the goal is to avoid some preprocessing that happens before revset parsing, we cannot simply implement it as a revset predicate. There was other approaches discussed over the mailing-list but they were less convincing. Having a configuration flag to disable legacy lookup have been considered but discarded. There are too many common uses of ambiguous identifier (eg: '+', '-' or '..') to have the legacy lookup mechanism turned off. In addition, the approach can control the parsing of each revset, making it more flexible. For example, a revset used as the value of an existing configuration option (eg: pushrev) could enforce its resolution as a revset (by using the prefix) while user inputs would still use the legacy lookup. In addition of offering a way to unambiguously input a revset, this prefix allow skipping the name lookup providing a significant speedup in some case.

revset: add more test to show current behaviors with label looking like revset There are very few constraints on what character can be put into tags and other labels. We add more tests showing some of extreme cases that user can currently use.
