This is more difficult than it should be IMO. In -ms, the indent is  
controlled by the number register \n[\n[.ev]:li] — so it can be  
handled per-environment. The global environment indent is \n[0:li]  
(zero, not O). But this does allow you to control indentation.

The heading macros (.NH, .SH) call SH-NO-TAG to set things up, so you  
can reset the indents there. This bit of code should give you the idea:

.\" ------------- set up indents --------------
.nr IN 5n
.am address@hidden
.if '\\n[.ev]'0' .nr \\n[.ev]:li (u;\\n[IN])
..
.nr 0:li \n[IN]
.am SH-NO-TAG
.in 0
..
.\" ------------- the document --------------
.NH 1
This Is a Test
.LP
This is a test, this is only a test.
.NH 2
Conditions
.LP
If this was an actual document,
there would have been something useful here.
.\" -------------- EOF --------------
