parsers: fix compiler errors on MSVC 2008
This broke in
3681de20b0a7.
sshpeer: only print out 'running ssh' messages in debug mode (BC)
Previously, if another command was run with --verbose, and for whatever reason
that invoked sshpeer, we'd get a 'running ssh' message from sshpeer. This extra
line would interfere with that command's output and cause dumb parsers to
break.
For example, hg annotate can be run with --verbose to get full usernames. This,
combined with the third-party remotefilelog extension which can cause ssh
connections to be created, leads to an extra 'running ssh' line that breaks
most parsers.
This patch is (BC) because hg pull --verbose will no longer print out exactly
what ssh command it is running.
No tests are affected by this change.
merge: mark mergestate as dirty when resolve changes _state
Correctness - no visible difference so far.
backout: improve confusing 'cannot backout change on a different branch' abort
These days 'branch' usually refer to a named branch.
Instead, abort with 'cannot backout change that not is an ancestor'.
config: set a 'source' in most cases where config don't come from file but code
Some extensions set configuration settings that showed up in 'hg showconfig
--debug' with 'none' as source. That was confusing.
Instead, they will now tell which extension they come from.
This change tries to be consistent and specify a source everywhere - also where
it perhaps is less relevant.
