wireproto: improve docstring for "hello"
Differential Revision: https://phab.mercurial-scm.org/D2217
#testcases lfsremote-on lfsremote-off
#require serve
This test splits `hg serve` with and without using the extension into separate
tests cases. The tests are broken down as follows, where "LFS"/"No-LFS"
indicates whether or not there are commits that use an LFS file, and "D"/"E"
indicates whether or not the extension is loaded. The "X" cases are not tested
individually, because the lfs requirement causes the process to bail early if
the extension is disabled.

$ hg init server
$ SERVER_REQUIRES="$TESTTMP/server/.hg/requires"
Skip the experimental.changegroup3=True config. Failure to agree on this comes
first, and causes a "ValueError: no common changegroup version" or "abort:
HTTP Error 500: Internal Server Error", if the extension is only loaded on one
side. If that *is* enabled, the subsequent failure is "abort: missing processor
for flag '0x2000'!" if the extension is only loaded on one side (possibly also
masked by the Internal Server Error message).

non-lfs content, and the extension state controlled by #testcases.

Since no lfs content has been added yet, the push is allowed, even when the
extension is not enabled remotely.

Case #3: client with lfs content and the extension enabled; server with
non-lfs content, and the extension state controlled by #testcases. The server
should have an 'lfs' requirement after it picks up its first commit with a blob.
$ echo 'this is a big lfs file' > lfs.bin
$ hg ci -Aqm 'lfs'
$ grep 'lfs' .hg/requires $SERVER_REQUIRES
.hg/requires:lfs
#if lfsremote-off
$ hg push -q
abort: required features are not supported in the destination: lfs
(enable the lfs extension on the server)

#else
$ hg push -q
#endif

The difference here is the push failed above when the extension isn't
enabled on the server.
$ hg identify http://localhost:$HGPORT

1477875038c6 (lfsremote-off !)
Don't bother testing the lfsremote-off cases- the server won't be able
to launch if there's lfs content and the extension is disabled.
