Make earlygetopt return a list of all option values, use the last value.
This fixes:
"hg -R" showing a useful error instead of traceback
"hg -R foo --repository bar" using bar instead of foo
And provides a way for other users of earlygetopt to accept more than
one value.
Basic install:
$ make # see install targets
$ make install # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg # see help
