formatting: drop a few extra double quotes in docstrings

These were made obvious by the reformatting in D9430.

A python hook for "hg fix" that prints out the number of files and revisions
that were affected, along with which fixer tools were applied. Also checks how
many times it sees a specific key generated by one of the fixer tools defined
below.

  $ cat >> $TESTTMP/postfixhook.py <<EOF
  > import collections
  > def file(ui, repo, rev=None, path=b'', metadata=None, **kwargs):
  >   ui.status(b'fixed %s in revision %d using %s\n' %
  >             (path, rev, b', '.join(metadata.keys())))
  > def summarize(ui, repo, replacements=None, wdirwritten=False,
  >               metadata=None, **kwargs):
  >     counts = collections.defaultdict(int)
  >     keys = 0
  >     for fixername, metadatalist in metadata.items():
  >         for metadata in metadatalist:
  >             if metadata is None:
  >                 continue
  >             counts[fixername] += 1
  >             if 'key' in metadata:
  >                 keys += 1
  >     ui.status(b'saw "key" %d times\n' % (keys,))
  >     for name, count in sorted(counts.items()):
  >         ui.status(b'fixed %d files with %s\n' % (count, name))
  >     if replacements:
  >         ui.status(b'fixed %d revisions\n' % (len(replacements),))
  >     if wdirwritten:
  >         ui.status(b'fixed the working copy\n')
  > EOF

Some mock output for fixer tools that demonstrate what could go wrong with
expecting the metadata output format.

  $ printf 'new content\n' > $TESTTMP/missing
  $ printf 'not valid json\0new content\n' > $TESTTMP/invalid
  $ printf '{"key": "value"}\0new content\n' > $TESTTMP/valid

Configure some fixer tools based on the output defined above, and enable the
hooks defined above. Disable parallelism to make output of the parallel file
processing phase stable.

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > fix =
  > [fix]
  > metadatafalse:command=cat $TESTTMP/missing
  > metadatafalse:pattern=metadatafalse
  > metadatafalse:metadata=false
  > missing:command=cat $TESTTMP/missing
  > missing:pattern=missing
  > missing:metadata=true
  > invalid:command=cat $TESTTMP/invalid
  > invalid:pattern=invalid
  > invalid:metadata=true
  > valid:command=cat $TESTTMP/valid
  > valid:pattern=valid
  > valid:metadata=true
  > [hooks]
  > postfixfile = python:$TESTTMP/postfixhook.py:file
  > postfix = python:$TESTTMP/postfixhook.py:summarize
  > [worker]
  > enabled=false
  > EOF

See what happens when we execute each of the fixer tools. Some print warnings,
some write back to the file.

  $ hg init repo
  $ cd repo

  $ printf "old content\n" > metadatafalse
  $ printf "old content\n" > invalid
  $ printf "old content\n" > missing
  $ printf "old content\n" > valid
  $ hg add -q

  $ hg fix -w
  ignored invalid output from fixer tool: invalid
  fixed metadatafalse in revision 2147483647 using metadatafalse
  ignored invalid output from fixer tool: missing
  fixed valid in revision 2147483647 using valid
  saw "key" 1 times
