gitweb, monoblue: break long line in map file

coal, paper: add newlines when displaying a file in hgweb The newlines make the HTML somewhat readable and gives much smaller, readable diffs when the tests change.

test-highlight: decouple test from get-with-headers.py The test copied get-with-headers.py from $TESTDIR and committed it to a test repository. The test output therefore depended unnecessarily on the exact content of get-with-headers.py. It has now been replaced with another small Python script.
