[issue617] TypeError if hgmerge blows up for "hg debuginstall"

[Bill Sommerfeld]

New submission from Bill Sommerfeld <sommerfeld at sun.com>:

for an (as yet un-root-caused) reason, my $PATH is causing hgmerge to screw up;
this has exposed a bug in an error path in the "debuginstall" tests which causes
it to throw an exception due to a format string mismatch.   

bug appears to be present in 0.9.3 and 0.9.4

See attachment for patch.
