(And dpkg-shlibdeps actually generates the dependency.)
I think an | *would* be ok but it is very hard to generate it well
using dpkg-shlibdeps. You might end up with these additional shlibs
pluginA: foo | bar, blah
Which does not seem to be properly translateable into a valid single
fasel|(foo | bar, blah) Depends relation.
You could move the plugin's additional dependencies into Recommends,
using "dpkg-shlibdeps -vRecommends" but as the program would not work
without any plugin packaging them separately indeed seems to be the
 fasel|foo|bar, fasel| blah does not work since it allows
installing blah with fasel instead of either foo or bar. ;-)
