I like to be very strict with things like quotes (and underscores in this c=
ase), so I would probably use:

irb> str
=3D> "asdf asdf _asdf asd_ asdf _ash \nash_ h"
irb> str.gsub(/_([^_]+)_/, "<i>\\1</i>")
=3D> "asdf asdf <i>asdf asd</i> asdf <i>ash \nash</i> h"

That seems to work like I would expect it to---I'm just coming over from Pe=
rl...
