config.txt: document behavior of backslashes in subsections
Unrecognized escape sequences are invalid in values:
$ git config -f - --list <<EOF
[foo]
bar = "\t\\\y\"\u"
EOF
fatal: bad config line 2 in standard input
But in subsection names, the backslash is simply dropped if the
following character does not produce a recognized escape sequence:
$ git config -f - --list <<EOF
[foo "\t\\\y\"\u"]
bar = baz
EOF
foo.t\y"u.bar=baz
Although it would be nice for subsection names and values to have
consistent behavior, changing the behavior for subsection names is a
nonstarter since it would cause existing, valid config files to
suddenly be interpreted differently.
