hg log --limit 1 file would do the trick only for the given file, so if 
a repository has n files this command would have to be run n times. for 
projects having more than 1000 files this doesn't sound reasonable when 
you have to get this information e.g. from java parsing the output of 
1000 log commands. running hg log with parsable list of files might 
enough, but it's still not the point.

IMO Mercurial lacks the feature that would easily indicate last 
modification revision. SVN and CVS provide an easy way to discover e.g 
last author of a file. It seems that in Mercurial there's no such thing 
as a pair 'file last_revision' (may be relative to the working 
directory), but that makes a lot of sense.
