highlight: guess by text when path name is ambiguous
Although the docs claim that guess_lexer_for_filename will fall back
to using file data, my ubuntu 7.10 pygments library seems to ignore
the text argument. So call guess_lexer explicitly on failure.
Basic install:
$ make # see install targets
$ make install # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg # see help
