The goal of this patch is to add the IDs of the parents of applied MQ patches
into the patch file headers whenever qnew or qrefresh are run.
This will serve as a reminder of when the patches last applied cleanly and
will let us do more intelligent things in the future, such as:
* Resolve conflicts found when qpushing to a new location by merging
instead of simply showing rejects.
* Display better diffs of versioned MQ patches because we can tell how the
patched files have changed in the meantime.
Here are the new rules this patch introduces. They are checked in this order:
* If a patch currently has old, plain-style patch headers ("From:" and
"Date:") do not change the style or add any new headers.
* If the 'mq.plain' configuration setting is true, only plain-style
headers will be used for all MQ patches.
* qnew will initialize new patches with HG-style headers and fill in the
"# Parent" header with the appropriate parent node.
* qrefresh will refresh the "# Parent" header with the current parent of
the current patch.
Copy information was saved in a common loop, then refined in a git-only block.
The problem was the latter did filter out renames occuring in the current
patch and irrelevant to commit. In the non-git case, copy records still existed
in the dirstate, referencing removed files, making the commit to fail. Git and
non-git copy handling paths are now separated for simplicity.

pmezard expects
hg qref -s -X b
to apply the -X to the list of files in the patch, and thus remove b from the
patch.
That's how it worked before c302ef4372b2. That change seemed sensible, but it
wasn't...
mpm says
(17:22:30) pmezard_: kiilerix1: do you mean that -X should be forbidden with -s ?
(17:22:54) pmezard_: kiilerix1: and --include too
(17:23:03) mpm: No because you should be able to say hg qref -s foo* -X foo-bar
so mpm expects
hg qref -s -X b *
to apply the -X to the list of files in the working directory, and thus don't
include b in the patch
This patch tries to make both usecases work by creating a matchfn which uses
the include/excludes but not the filelist.
'hg qrefresh --short file.txt' now adds changes made to file.txt to current
patch.
This builds on a patch for implementing --amend by Kirill Smelkov as discussed
in issue933.
FIXME: Why do mq refresh have two matchers if we only need one?
We'd mistakenly made the -p option always on, which meant there was no
way to turn it off. It also meant that we were sometimes splitting
multibyte characters in function name, which isn't a good default.
