util: adjust 'datapath' to be correct in a frozen OS X package
Apparently unlike py2exe, py2app copies the Mercurial source tree as-is to a
Contents/Resources subdirectory of an app bundle, and places its binary stub in
Contents/MacOS. (The Windows install has the 'hgext' and 'mercurial' modules in
'lib/library.zip', while the help and templates subdirectories have been moved
out of the mercurial directory to the root of the installation. I assume that
the python code living in a zip file is why "py2exe doesn't support __file__".)
Therefore, prior to this change, Mercurial in a frozen app bundle on OS X would
go looking for help *.txt, templates and locale info in Contents/MacOS, where
they don't exist.
There are only a handful of places that test for frozen, and not all of them are
wrong for OS X, so it seems wiser to handle them on a case by case basis, rather
that try to change mainfrozen(). The remaining cases are:
1) util.hgexecutable() wrongly points to the bundled python executable, and
affects $HG in util.system() launched processes (e.g. external hooks)
2) util.hgcmd() wrongly points to the bundled python executable, but it seems
to only affect 'hg serve -d'
3) hook._pythonhook() may be OK, since I didn't see anything outrageous when
printing sys.path from an internal hook. I'm not sure if this special
case is needed on OS X though.
4) sslutil._plainapplepython() is OK, because sys.executable is not
/usr/bin/python, nor is it in /System/Library/Frameworks

"""syntax highlighting for hgweb (requires Pygments) It depends on the Pygments syntax highlighting library: http://pygments.org/ There are the following configuration options:: [web] pygments_style = <style> (default: colorful) highlightfiles = <fileset> (default: size('<5M')) highlightonlymatchfilename = <bool> (default False) ``highlightonlymatchfilename`` will only highlight files if their type could be identified by their filename. When this is not enabled (the default), Pygments will try very hard to identify the file type from content and any match (even matches with a low confidence score) will be used.
