With the supplied bit of postscript, it's easy enough to write
a macro that takes the desired thickness and distance from the
baseline as arguments.

For my purposes, the sentence space issue can be resolved by setting
the sentence space to the default before underlining, and restoring
it afterwards.  As to changing fonts while underlining, it's hard to
imagine a situation in which it's likely to happen.  Underlining
should at best be an occasional effect, IMHO.  Still, one likes to
have solutions that cover every possibility.
