Printing of "\n" in error messages is broken
The code excerpts in error messages from GHC 7.8.3 are misformatted when the original code contains the string "\n" - the \n escape is simply lost. Example with GHCi:
Prelude> 1+"\n"
<interactive>:2:2:
No instance for (Num [Char]) arising from a use of `+'
In the expression: 1 + ""
In an equation for `it': it = 1 + ""
The printing of the string "\n " is also strangely formatted, although technically equivalent:
Prelude> 1+"\n "
<interactive>:3:2:
No instance for (Num [Char]) arising from a use of `+'
In the expression:
1
+ "\n\
\ "
In an equation for `it':
it
= 1
+ "\n\
\ "
