test of sync-doc fails on Git-for-Windows

[iraytrace]

When running "make test" or "test.sh" the first test for "sync-doc" fails when running under "git for windows". This is likely due to the fact that windows prefers CRLF line endings, and git produces warnings of the form:

warning: LF will be replaced by CRLF in git-issue.1.
The file will have its original line endings in your working directory
warning: LF will be replaced by CRLF in git-issue.sh.
The file will have its original line endings in your working directory
