Did you install Git for Windows with EOL conversion option set to
_anything_ but "checkout as-is, commit as-is"?  If so, please
reconfigure your Git to use that.  To that effect, please _remove_
from your .gitconfig files (there might be more than one) _any_
settings of the following variables:

  core.eol
  core.safecrlf
  core.autocrlf

Then remove your Emacs Git repository and re-clone it again.

The upshot of all that is to have the EOL format of each file in the
repository exactly as it is on a Unix system.  That is the only sane
way of using Git on Windows for a project that supports multiple
platforms and includes files with both Unix-style and DOS-style EOLs
in the repository.

I'm guessing this is the result of the same problem with EOL format:
the Texinfo source files in doc/lispref/*.texi have DOS CRLF EOL
format, but your 'makeinfo' utility is from MSYS and expects Unix
EOLs.  Note how the closing ' character is displayed at the beginning
of the line, instead of being after `fn -- that's because there's a CR
character after `fn.
