cleanup: remove pointless r-prefixes on single-quoted strings
This is the promised second step on single-quoted strings. These had
existed because our source transformer didn't turn r'' into b'', so we
had tagged some strings as r-strings to get "native" strings on both
Pythons. Now that the transformer is gone, we can dispense with this
nonsense.
Methodology:
I ran
hg locate 'set:added() or modified() or clean()' | egrep '.*\.py$' | xargs egrep --color=never -n -- \[\^b\]\[\^a-z\]r\'\[\^\'\\\\\]\*\'\[\^\'\
in an emacs grep-mode buffer, and then used a keyboard macro to
iterate over the results and remove the r prefix as needed.
# skip-blame removing unneeded r prefixes left over from Python 3 migration.

Mercurial supports generating standalone "bundle" files that hold repository data. These "bundles" are typically saved locally and used later or exchanged between different repositories, possibly on different machines. Example commands using bundles are :hg:`bundle` and :hg:`unbundle`. Generation of bundle files is controlled by a "bundle specification" ("bundlespec") string. This string tells the bundle generation process how to create the bundle. A "bundlespec" string is composed of the following elements: type A string denoting the bundle format to use. compression Denotes the compression engine to use compressing the raw bundle data. parameters Arbitrary key-value parameters to further control bundle generation. A "bundlespec" string has the following formats: <type> The literal bundle format string is used. <compression>-<type> The compression engine and format are delimited by a hyphen (``-``). Optional parameters follow the ``<type>``. Parameters are URI escaped ``key=value`` pairs. Each pair is delimited by a semicolon (``;``). The first parameter begins after a ``;`` immediately following the ``<type>`` value. Available Types =============== The following bundle <type> strings are available: v1 Produces a legacy "changegroup" version 1 bundle. This format is compatible with nearly all Mercurial clients because it is the oldest. However, it has some limitations, which is why it is no longer the default for new repositories. ``v1`` bundles can be used with modern repositories using the "generaldelta" storage format. However, it may take longer to produce the bundle and the resulting bundle may be significantly larger than a ``v2`` bundle. ``v1`` bundles can only use the ``gzip``, ``bzip2``, and ``none`` compression formats. v2 Produces a version 2 bundle. Version 2 bundles are an extensible format that can store additional repository data (such as bookmarks and phases information) and they can store data more efficiently, resulting in smaller bundles. Version 2 bundles can also use modern compression engines, such as ``zstd``, making them faster to compress and often smaller. Available Compression Engines ============================= The following bundle <compression> engines can be used: .. bundlecompressionmarker Examples ======== ``v2`` Produce a ``v2`` bundle using default options, including compression. ``none-v1`` Produce a ``v1`` bundle with no compression. ``zstd-v2`` Produce a ``v2`` bundle with zstandard compression using default settings. ``zstd-v1`` This errors because ``zstd`` is not supported for ``v1`` types.
