From 95405ba6cf7adeaa4a066e8a3a1b76b73f7b9341 Mon Sep 17 00:00:00 2001 From: Alex Riesen Date: Wed, 13 May 2009 20:08:53 +0200 Subject: [PATCH] Quote LF in urls git fetch saves in FETCH_HEAD The fmt-merge-msg does a strong syntax checking of its input and fails with if it is incorrect. The LF character is the only character important for fmt-merge-msg. As the url in FETCH_HEAD plays only informational role, a quoted representation of the url should be good and true enough. The url often comes from either user-editable config or command line, so it is reasonable to expect all kinds of characters in it, including the characters which the format of FETCH_HEAD considers special (line separator in this case). Noticed and reported by Hugo Mildenberger.
