Others have already provided some replies, but FWIW searching for
mentions of related problems seen by other projects finds e.g.:
https://github.com/reconquest/import.bash/issues/2
https://community.perforce.com/s/article/2973
Reading and summarizing these and the like, it appears that:
Git on Windows defaults to using CRLF for text files ("On windows
systems core.autocrlf is normally set to "true" globally.")
To avoid the problem, one can "do a "git -c core.autocrlf=input clone
..." and finally set core.autocrlf=input locally".
As a workaround, it can be possible to "make use of "set -o igncr"
(warning: cygwin bash only!)". It may also be required to "export
SHELLOPTS" for this to work.
As another workaround, the project could "add .gitattributes file [...]
and force git to handle shell scripts eol=lf". Maybe we should?
