doc/tmac.nh (ED): Don't dedent below zero.

Browse Source 
This quietens several warnings from GNU troff in the "range" category.

troff: backtrace: './doc/tmac.nh':92: macro 'ED'
troff: backtrace: file './doc/Guidebook.mn':5950
troff:./doc/Guidebook.mn:5950: warning: treating -120u indentation as
zero

Unfortunately, the similar `ed` macro in Bishop's "mn" package
contributes several more.

But with this change (and its forerunners in this series), the NetHack
Guidebook is now warning-free with "-wall -Wtab -Wrange" ("mn" has
problems with tab characters too), even with the increasingly fastidious
syntactical checks of the forthcoming groff 1.24 release.
