[TxMt] TextMate accidentally put in blank/new lines every other line

[Marius Hofert]

Dear all,

I opened a file I recently worked on [.R] and realized that there is a blank/new line every other line. So instead of ...
a b c d e
f g h i j k
l m n o p
... I have ...
a b c d e

f g h i j k

l m n o p

I must have accidentally hit some key combination before I save the file. Is this possible? Is there any simple way to undo this? Going through by hand and even with find next + replace it's tedious.

Cheers,

Marius
