Description jwatte 2012-05-21 02:19:47 UTC
Bug https://bugzilla.xamarin.com/show_bug.cgi?id=3235 mentions something that is dismissed as a "downstream bug in the Unity JS plugin."
That's not at all the case -- the bug is reproducible in plain MonoDevelop, at least when editing C++ code. The trick is to have "auto-format code" turned on.

Reproduction is simple:
1) Type:
abcd
efgh
ijkl

2) Put the cursor before "a" and press shift-linedown to select an entire line

3) Copy

4) Put the cursor before "i"

5) Paste

You will now see that the "ijkl" line starts with TWO "i" characters.

Apparently this happens on MacOS X in 2.8, and it also happens in Linux in 2.6 (which is the version shipped with Mint 12, which is the current distribution -- you might want to poke them about updating...)
At a minimum, please turn on auto-reformatting of code and try this experiment in 3.0 to see if it's still there. My guess is it is.

Works in master/3.0.

(At least tested in master)
