Try:

c:\cygwin64\bin\dash -c '/bin/getclip | /bin/tr -s "\r\n" " " | 
/bin/putclip'

e.g.

$ mkshortcut -D -n clip-strip /bin/dash -a "-c '/bin/getclip | /bin/tr 
-s \"\r\n\" \" \" | /bin/putclip'"

works and doesn't hang with latest Cygwin.

Note: tr has accepted C escapes for decades (Turbo C days), and use of 
"\012\015" == "\n\r" is anachronistic, rarely encountered compared to 
older systems' and network protocols' text line ending "\r\n", where 
both may be repeated, or only the "\n" for skipping lines.
