When we use the clipboard here's what happens:

Bash makes (1) very hard because it doesn't allow storing variables
with null characters, and makes it unnecessarily verbose for
remembering if the output of a command did or did not have a trailing
newline. For this reason, we instead treat the contents of the current
clipboard in (1) as generic binary data. As such, we store it
temporarily in base64 to work around bash's restrictions.
Hi Jason,
Thanks for responding. So if I understand correctly, the current
"base64" implementation will preserve any newlines when copying and
restoring the previous contents of the clipboard. However, replacing the
"base64" or "base64 -d" command with "tr -d '\n' " will remove any
newlines when restoring the previous contents to the clipboard, so the
functionality is not exactly the same.
Still, I noticed that a month ago on the mailing list some people
expressed interest in simplifying the clip() function by just emptying
the clipboard after 45 seconds. Doing this would remove the "base64"
dependency in cygwin/mingw/msys/msysgit. Do you have any thoughts on this?
P.S. Do you have a preference about top-posting or bottom-posting email
replies on the listserv?
Thanks,
