localrepo: check HG_PENDING strictly

Before this patch, checking HG_PENDING for changelog in localrepo.py
might cause unintentional reading unrelated '00changelog.i.a' in,
because HG_PENDING is checked by str.startswith().

An external hook spawned by inner repository in nested ones satisfies
this condition.

This patch uses txnutil.mayhavepending() to check HG_PENDING strictly.

BTW, this patch may cause failure of bisect in the repository of
Mercurial itself, if examination at bisecting assumes that an external
hook can see all pending changes while nested transactions across
repositories.

This invisibility issue will be fixed by subsequent patch, which
allows HG_PENDING to refer multiple repositories.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing:

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
