I would like to do
svn commit -m \"\"
But message should have two lines:
Commit by: firstuser
Bug track: 92
You can define the newline as follows:
set newline=^& echo.
Then, you can use the newline in other statements, like this: (no quotes)
echo This is the first line%newline%This is the second line
echo "This is the first line"%newline%"This is the second line"
or with an extra caret, like this:
set text=This is the first line^%newline%This is the second line
Perhaps you can play with that, but mind the combination with quotes!
