run-tests: redefine --with-hg so it takes the 'hg' script to run.
- in parseargs(), check that --with-hg value is valid
- add handy --local option for "--with-hg=../hg"
- ensure that we always set PATH and PYTHONPATH (not just
when doing a temporary install)
- override any existing PYTHONPATH, so test success does not
depend on whatever happens to be in the caller's environment
- give tests a little more control by exporting $PYTHON to the
environment; needed by test-convert and test-mergetool when
they run hg with a stripped-down $PATH
Also, add a big comment explaining all the corner cases to test for the
next person who tries to modify this script.

hg falabala [OPTION]... [FILE]...
use 'echo' to diff repository (or selected files)
Show differences between revisions for the specified
files, using the 'echo' program.
When two revision arguments are given, then changes are
shown between those revisions. If only one revision is
specified then that revision is compared to the working
directory, and, when no revisions are specified, the
working directory files are compared to its parent.
options:
-o --option pass option to comparison program
-r --rev revision
-c --change change made by revision
-I --include include names matching the given patterns
-X --exclude exclude names matching the given patterns
use "hg -v help falabala" to show global options
