sparse: remove custom hash matcher
With the recent change to always use repr(), this function was
functionally identical to the version in fsmonitor it was
replacing. So remove it.

"""allow sparse checkouts of the working directory (EXPERIMENTAL)
(This extension is not yet protected by backwards compatibility
guarantees. Any aspect may break in future releases until this
notice is removed.)
This extension allows the working directory to only consist of a
subset of files for the revision. This allows specific files or
directories to be explicitly included or excluded. Many repository
operations have performance proportional to the number of files in
the working directory. So only realizing a subset of files in the
working directory can improve performance.
Sparse Config Files
-------------------
The set of files that are part of a sparse checkout are defined by
a sparse config file. The file defines 3 things: includes (files to
include in the sparse checkout), excludes (files to exclude from the
sparse checkout), and profiles (links to other config files).
The file format is newline delimited. Empty lines and lines beginning
with ``#`` are ignored.
Lines beginning with ``%include `` denote another sparse config file
to include. e.g. ``%include tests.sparse``. The filename is relative
to the repository root.
The special lines ``[include]`` and ``[exclude]`` denote the section
for includes and excludes that follow, respectively. It is illegal to
have ``[include]`` after ``[exclude]``. If no sections are defined,
entries are assumed to be in the ``[include]`` section.
Non-special lines resemble file patterns to be added to either includes
or excludes. The syntax of these lines is documented by :hg:`help patterns`.
Patterns are interpreted as ``glob:`` by default and match against the
root of the repository.
Exclusion patterns take precedence over inclusion patterns. So even
if a file is explicitly included, an ``[exclude]`` entry can remove it.
For example, say you have a repository with 3 directories, ``frontend/``,
``backend/``, and ``tools/``. ``frontend/`` and ``backend/`` correspond
to different projects and it is uncommon for someone working on one
to need the files for the other. But ``tools/`` contains files shared
between both projects. Your sparse config files may resemble::
# frontend.sparse
frontend/**
tools/**
# backend.sparse
backend/**
tools/**
Say the backend grows in size. Or there's a directory with thousands
of files you wish to exclude. You can modify the profile to exclude
certain files::
[include]
backend/**
tools/**
[exclude]
tools/tests/**

The sparse command is used to make the current checkout sparse.
This means files that don't meet the sparse condition will not be
written to disk, or show up in any working copy operations. It does
not affect files in history in any way.
Passing no arguments prints the currently applied sparse rules.
--include and --exclude are used to add and remove files from the sparse
checkout. The effects of adding an include or exclude rule are applied
immediately. If applying the new rule would cause a file with pending
changes to be added or removed, the command will fail. Pass --force to
force a rule change even with pending changes (the changes on disk will
be preserved).
--delete removes an existing include/exclude rule. The effects are
immediate.
--refresh refreshes the files on disk based on the sparse rules. This is
only necessary if .hg/sparse was changed by hand.
--enable-profile and --disable-profile accept a path to a .hgsparse file.
This allows defining sparse checkouts and tracking them inside the
repository. This is useful for defining commonly used sparse checkouts for
many people to use. As the profile definition changes over time, the sparse
checkout will automatically be updated appropriately, depending on which
changeset is checked out. Changes to .hgsparse are not applied until they
have been committed.
--import-rules accepts a path to a file containing rules in the .hgsparse
format, allowing you to add --include, --exclude and --enable-profile rules
in bulk. Like the --include, --exclude and --enable-profile switches, the
changes are applied immediately.
--clear-rules removes all local include and exclude rules, while leaving
any enabled profiles in place.
Returns 0 if editing the sparse checkout succeeds.
