test-treediscovery: fix escaping for both dash and bash

A '\n' on the command line is turned into a newline by dash, but kept
as-is by bash, which resulted in a syntax error in the config file.

Luckily, dash wont turn '\n' into a newline when it is part of a
here-doc, so we can write the config file using that technique.

#!/usr/bin/env python

__doc__ = """Same as `echo a >> b`, but ensures a changed mtime of b.
Without this svn will not detect workspace changes."""

import sys, os

text = sys.argv[1]
fname = sys.argv[2]

f = open(fname, "ab")
try:
    before = os.fstat(f.fileno()).st_mtime
    f.write(text)
    f.write("\n")
finally:
    f.close()
inc = 1
now = os.stat(fname).st_mtime
while now == before:
    t = now + inc
    inc += 1
    os.utime(fname, (t, t))
    now = os.stat(fname).st_mtime
