What do you mean you want to avoid cloning the repository?  One of the key
benefits of a DVCS like Mercurial is the ease with which you can branch and
merge again.  If you are keeping your master repository on media that you
want to minimize writes to, then you want to plug it into a computer, create
a local clone on that computer, work/build on it, make your commits, and
when you're done with the computer, 'hg push' in the local clone will put
everything you did locally back onto the thumb drive, with minimal writing
to the flash memory.

0.9.4 is almost three and a half years out of date.  You should upgrade to
1.7.1, there are countless benefits.
