fix #143 by giving synonyms horizontal clearance

[jzacsh]

this clear: right that's being replaced certainly seems to be intended to do the same thing, but (see issue #143 screenshots):

• a. I've not been able to confirm what it actually does (perhaps it worked at some point, but it doesn't seem to now)
• b. I've given man pages a cursory glance and I can't see any harm in having both (only effect is the fix of 143).
