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.

# Description
# -----------
# This script generates a tcsh source file to support completion
# of Mercurial commands and options.
#
# Instruction:
# -----------
# Run this script to generate the tcsh source file, and source
# the file to add command completion support for Mercurial.
#
#    tcsh% tcsh_completion.sh FILE
#    tcsh% source FILE
#
# If FILE is not specified, tcsh_completion will be generated.
#
# Bugs:
# ----
# 1. command specific options are not supported
# 2. hg commands must be specified immediately after 'hg'.
