Comment (by hvr):

 I've investigated a bit, the culprit seems to be
 4f764d06f3b9899c09a6a459a22d4be694ee45d9 where the following diff fragment
 caused the macro-precedence to be reversed accidentally:

 {{{#!diff
 -      ':' : rest -> (rest, builtin_commands) -- "::" selects a builtin
 command
 -      _ -> (str', macros ++ builtin_commands) } -- otherwise prefer
 macros
 +      ':' : rest -> (rest, ghci_cmds) -- "::" selects a builtin command
 +      _ -> (str', ghci_cmds ++ macros) } -- otherwise prefer macros
 }}}
