help: document the server capabilities added by the LFS extension I didn't bother marking these experimental because it references the extension that is already marked experimental.

commands: adjust metavariables as appropriate Apart from looking better in hg help command, these strings are also helpful when generating shell completions programmatically.

narrow: when widening, don't include manifests the client already has When widening, we already don't include the changelog (since f1844a10ee19) and files that the client already has (since c73c7653dfb9). However, we still include all manifests needed for the new narrowspec. When using flat manifests, that means we resend all the manifests even though the client necessarily has all of them. For tree manifests, we unnecessarily resend the root manifests and any subdirectory manifests that the client already has. This patch makes it so we no longer resend manifests that the client already has. It does so by passing an extra matcher to the changegroup packer and it uses that for filtering out directories matching the old matcher's visitdir(). For consistency between directories and files, it also makes the filtering of files look at both old and new matcher rather than passing in a diff matcher as we did before.

tests: add test for widening from an empty clone Narrow clones that track no paths currently don't even include the root manifest (which is the only manifest when using flat manifests). That means that when we widen from such a clone, we need to make sure that we send the root manifest (and other manifests if using tree manifests). That currently works because we always resend all manifest that match the new narrowspec. However, we're about to stop resending manifests that the client already has and there's a risk of this breaking then, so let's add a test.

revisions: when using prefixhexnode, ensure we prefix "0" Previously, if using `experimental.revisions.disambiguatewithin` (and it didn't include rev0), and '0' was the shortest identifier in that disambiguation set, we printed it as the shortest *without* a prefix. This was because we had logic to determine "if the prefix is a pure integer, but starts with 0, we don't need to prefix with 'x': 01 is not a synonym for revision #1", but didn't handle the case where prefix == 0 (which is a pure integer, and starts with 0... but it *is* "rev0").
