color: support a different color mode when the pager is active

MSYS on Windows has a terminal that supports the "win32" color mode
(which "auto" properly detects for us). However, a popularily configured
pager in that environment (GNU less) only supports the "ansi" color
mode.

This patch teaches color about a new config option: pagermode. It
behaves like "mode" but is only consulted when the pager is active for
the current command. MSYS users can now set "pagermode = ansi" and get a
colorful experience that just works. Previously, MSYS users would have
to live without color when using GNU less as the pager, would have to
manually configure the pager to attend every command, or would have
gibberish if "ansi" was used without the pager.

Test that the syntax of "unified tests" is properly processed
==============================================================

Simple commands:

  $ echo foo
  foo
  $ printf 'oh no'
  oh no (no-eol)
  $ printf 'bar\nbaz\n' | cat
  bar
  baz

Multi-line command:

  $ foo() {
  >     echo bar
  > }
  $ foo
  bar

Return codes before inline python:

  $ sh -c 'exit 1'
  [1]

Doctest commands:

  >>> print 'foo'
  foo
  $ echo interleaved
  interleaved
  >>> for c in 'xyz':
  ...     print c
  x
  y
  z
  >>> print
  
  >>> foo = 'global name'
  >>> def func():
  ...     print foo, 'should be visible in func()'
  >>> func()
  global name should be visible in func()
  >>> print '''multiline
  ... string'''
  multiline
  string

Regular expressions:

  $ echo foobarbaz
  foobar.* (re)
  $ echo barbazquux
  .*quux.* (re)

Globs:

  $ printf '* \\foobarbaz {10}\n'
  \* \\fo?bar* {10} (glob)

Literal match ending in " (re)":

  $ echo 'foo (re)'
  foo (re)

Windows: \r\n is handled like \n and can be escaped:

#if windows
  $ printf 'crlf\r\ncr\r\tcrlf\r\ncrlf\r\n'
  crlf
  cr\r (no-eol) (esc)
  \tcrlf (esc)
  crlf\r (esc)
#endif

Combining esc with other markups - and handling lines ending with \r instead of \n:

  $ printf 'foo/bar\r'
  fo?/bar\r (no-eol) (glob) (esc)
#if windows
  $ printf 'foo\\bar\r'
  foo/bar\r (no-eol) (glob) (esc)
#endif
  $ printf 'foo/bar\rfoo/bar\r'
  foo.bar\r \(no-eol\) (re) (esc)
  foo.bar\r \(no-eol\) (re)

testing hghave

  $ "$TESTDIR/hghave" true
  $ "$TESTDIR/hghave" false
  skipped: missing feature: nail clipper
  [1]
  $ "$TESTDIR/hghave" no-true
  skipped: system supports yak shaving

Conditional sections based on hghave:

#if true

  $ echo skipped
#endif

#if false
  $ echo skipped

  $ echo tested
  tested

#if no-false
  $ echo tested
  tested

  $ echo skipped
#endif

#if no-true
  $ echo skipped

  $ echo tested
