When filtering, "git show" is called in order to pull the commit message
from the git log. While slow, it makes certain that the message itself is
pulled correctly, including any escape characters that might be present.
This is flag should not be needed anymore, as gitinspector always uses
a reference point such as HEAD or some reivision when looking into the
repository (never the file structure directly).
The default behaviour is now not to localize the output, only the help
text and error messages (all the user interaction).
The way localized messages are fetched in the modules has been modified
as well; to allow for the ability to enable and disable the localization.
Just like in many GNU tools, it is now possible to pass an optional
boolean to some of the flags of gitinspector in the form;
--flag[=BOOL]
This gives us the ability to override options set via git-config.
For example; say we did the following:
git-config --global inspector.timeline true
We could then override this setting when running gitinspector by supplying:
./gitinspector.py --timeline=false
Implementing this was not a trivial task, as no command-line parser in
Python supports this by default (getopt, optparse, argparse). In order to
properly handle optional boolean arguments; some clever patching had to
be done to the command-line in combination with a callback function that
can handle boolean strings. To maintain compatibility with Python 2.6,
this was implemented using optparse (instead of argparse).
The gettext.install() functions supplies a way to force it to return
unicode which helps with compatibility between Python 2 & 3. To make it
work properly when merging those returned string with strings in the
different modules of gitinspector we also had to do some changes to make
sure all string literals are in unicode.
