localrepo: omit ".hgsubstate" also from "added" files
Before this patch, "localrepository.commit()" omits ".hgsubstate" from
"modified" (changes[0]) and "removed" (changes[2]) file list before
checking subrepositories, but leaves one in "added" (changes[1]) as it
is.
Then, "localrepository.commit()" adds ".hgsubstate" into "modified" or
"removed" list forcibly, according to subrepository statuses.
If "added" contains ".hgsubstate", the committed context will contain
two ".hgsubstate" in its "files": one from "added" (not omitted one),
and another from "modified" or "removed" (newly added one).
How many times ".hgsubstate" appears in "files" changes node hash,
even though revision content is same, because node hash calculation
uses the specified "files" directly (without duplication check or so).
This means that node hash of committed revision changes according to
existence of ".hgsubstate" in "added" at "localrepository.commit()".
".hgsubstate" is treated as "added", not only in accidental cases, but
also in the case of "qpush" for the patch adding ".hgsubstate".
This patch omits ".hgsubstate" also from "added" files before checking
subrepositories. This patch also omits ".hgsubstate" exclusion in
"qnew"/"qrefresh" introduced by changeset d666da075b91, because this
patch makes them meaningless.
"hg parents --template '{files}\n'" newly added to "test-mq-subrepo.t"
enhances checking unexpected multiple appearances of ".hgsubstate" in
"files" of created/refreshed MQ revisions.

'''browse command output with an external pager
To set the pager that should be used, set the application variable::
[pager]
pager = less -FRX
If no pager is set, the pager extensions uses the environment variable
$PAGER. If neither pager.pager, nor $PAGER is set, no pager is used.
You can disable the pager for certain commands by adding them to the
pager.ignore list::
[pager]
ignore = version, help, update
You can also enable the pager only for certain commands using
pager.attend. Below is the default list of commands to be paged::
[pager]
attend = annotate, cat, diff, export, glog, log, qdiff
Setting pager.attend to an empty value will cause all commands to be
paged.
If pager.attend is present, pager.ignore will be ignored.
To ignore global commands like :hg:`version` or :hg:`help`, you have
to specify them in your user configuration file.
The --pager=... option can also be used to control when the pager is
used. Use a boolean value like yes, no, on, off, or use auto for
normal behavior.
