mq: create patch file after commit to import diff of ".hgsubstate" at qrefresh
Even though the committed revision contains diff of ".hgsubstate", the
patch file created by qrefresh doesn't contain it, because:
- ".hgsubstate" is not listed up as one of target files of the patch
for reasons below, so diff of ".hgsubstate" is not imported into
patch file
- status of ".hgsubstate" in working directory is usually "clean"
- ".hgsubstate" is not specified explicitly by users
- the patch file is created before commit processing which updates
or creates ".hgsubstate" automatically, so there is no diff for it
at that time
This patch resolves this problem by:
- putting ".hgsubstate" into target list of the patch, if needed:
this allows "patch.diff()" to import diff of ".hgsubstate" into
patch file.
- creating the patch file after commit processing:
this updates ".hgsubstate" before "patch.diff()" invocation.
For the former fixing, this patch introduces "putsubstate2changes()"
to share same implementation with qnew. This is invoked only once per
qnew/qrefresh at most, so there is less performance impact.
This patch also omits "match" argument for "patch.diff()" invocation,
because "patch.diff()" ignores "match" if "changes" is specified.
