Enable trac to support multiline commit messages

[viktor@…]

Currently trac-post-commit-hook relies on the commit message being passed in the command line. That is a limitation both in size and in number of lines limited to one (at least it appeared so on my (sorry) windows environment - trac received only the first line of the commit message)

Attaching modified post-commit-hook, summary of changes:

• Add -f, —file to options
• if -m was not given, look for file given in -f, read all lines into a message, adding newlines.

This makes sure that:

• all newlines in the message are preserved
• all keywords in all lines are found.

I've started learning Python just doing this, so I haven't done any error checking (i.e. file exists, anything can be read from it etc.)

All you have to do is modify the svn post-commit script to store the commit message into a temporary file and replace -m message with -f filepath.

updated to trunk version, the previous was from 0.9.5

I guess we could get rid of this environment-specific issues if we move the calls to svnlook into the Python script, using the Python SWIG wrappers to access the Subversion repository.

See #1602 regarding the use of the commit hooks on Windows. There are scripts attached there that support multi-line messages.

Also, please don't attach full files. See TracDev/SubmittingPatches for a description of how to submit your changes.
