ui: restrict length of autogenerated blocked tags
Long autogenerated blocked tags tend to be because the command has an absolute
path; at Facebook, we've had a few where the tag is thousands of characters
long (in association with the mergedriver).
Change the default to use a suffix of a command as the default tag, limiting us
to 85 characters (for a 100 character tag). This is long enough to overflow a
standard terminal (thus be obviously autogenerated), but short enough to be
readable.
