run-tests: add substitution patterns for common '\' path output on Windows The goal is to reduce the amount of hand tuning of new/changed tests that is required on Windows. Since the OS prints the proper paths everywhere else, this is limited to Windows. These are based on the check-code rules that were dropped in 5feb782c7a95. There are some minor tweaks, because those were trying to detect '/' paths without a '(glob)' at the end, whereas these detect '\' paths. Also, it looks like the 'no changes made to subrepo' one was broke, because the path to the subrepo has been getting output but was not in the pattern. End anchors are dropped because '(glob)' is no longer required, but '(feature !)' annotations are a possibility. The 'saved backup bundle' pattern dropped from run-tests.py was simply carrying over the first capture group. The replace() method runs prior to evaluating '\1', but it wasn't doing anything because of the 'r' prefix on '\\'. The 'not recording move' entry is new, because I stumbled upon it searching for some of these patterns. There are probably others.

A new repository uses zlib storage, which doesn't need a requirement

  $ hg init default
  $ cd default
  $ cat .hg/requires
  dotencode
  fncache
  generaldelta
  revlogv1
  store

  $ touch foo
  $ hg -q commit -A -m 'initial commit with a lot of repeated repeated repeated text to trigger compression'
  $ hg debugrevlog -c | grep 0x78
      0x78 (x)  :   1 (100.00%)
      0x78 (x)  : 110 (100.00%)

  $ cd ..

Unknown compression engine to format.compression aborts

  $ hg --config experimental.format.compression=unknown init unknown
  abort: compression engine unknown defined by experimental.format.compression not available
  (run "hg debuginstall" to list available compression engines)
  [255]

A requirement specifying an unknown compression engine results in bail

  $ hg init unknownrequirement
  $ cd unknownrequirement
  $ echo exp-compression-unknown >> .hg/requires
  $ hg log
  abort: repository requires features unknown to this Mercurial: exp-compression-unknown!
  (see https://mercurial-scm.org/wiki/MissingRequirement for more information)
  [255]

  $ cd ..

#if zstd

  $ hg --config experimental.format.compression=zstd init zstd
  $ cd zstd
  $ cat .hg/requires
  dotencode
  exp-compression-zstd
  fncache
  generaldelta
  revlogv1
  store

  $ touch foo
  $ hg -q commit -A -m 'initial commit with a lot of repeated repeated repeated text'

  $ hg debugrevlog -c | grep 0x28
      0x28      :  1 (100.00%)
      0x28      : 98 (100.00%)

  $ cd ..

Specifying a new format.compression on an existing repo won't introduce data
with that engine or a requirement

  $ cd default
  $ touch bar
  $ hg --config experimental.format.compression=zstd -q commit -A -m 'add bar with a lot of repeated repeated repeated text'

  $ cat .hg/requires
  dotencode
  fncache
  generaldelta
  revlogv1
  store

  $ hg debugrevlog -c | grep 0x78
      0x78 (x)  :   2 (100.00%)
      0x78 (x)  : 199 (100.00%)
