By the way, "\n" is there only for nice looking output of git-config
for this variable. For config file you need only to escape end of line.

Errrr... what I meant is that you have to _quote_ value if it contains
comment character, compare
[string]
unquoted = a # b
quoted = "a # b"
not that you have to escape comment character '#'. But I forgot about
the fact that ## in your example is inside quotes anyway.
