partial file names in tags

[Bill Trost <trost@cloud.rain.com>]

I'm pretty strongly convinced that whacking off wily's startup
directory in the tag is a bad idea.  The problem I'm running into is
that I want to run a command on something in "the current pane".
Given a full filename, what I would do is type the command name at the
end of the tag, click button 1 on the filename, and then B2B1 on the
command.  However, if the filename is something like wily/pane.c, this
won't work, because the working directory for the command being run is
already "wily", so it ends up trying to access .../wily/wily/pane.c
and barfing.

I can mouse out just the filename, but I think it's still a lose.
Some approach that keeps valid filenames (with respect to the working
directory of the pane) in the tag seems necessary.

Opinions?
