config/fmt-merge-msg.txt: drop space in quote

We document how `merge.suppressDest` can be used to omit " into <branch
name>" from the title of the merge message. It is true that we omit the
space character before "into", but that lone double quote character
risks ending up on the wrong side of a line break, looking a bit out of
place. This currently happens with, e.g., 80-character terminals.

Drop that leading quoted space. The result should be just as clear about
how this option affects the formatted message.
