Follow-up Comment #8, bug #67571 (group groff): [comment #7 comment #7:] > the first "I: fold" renders with character flags of 0 > attached to the ':' character.
That is precisely the purpose of the first "I: fold". It is the "before"
exhibit. It should (and does) render the same way in all cases.
The second "I: fold" is the "after" exhibit. It follows the unconditional
.cflags call.
For this .cflags to have any observable effect, however, the [EOS] class must
already be defined. If it is, this second "I: fold" will render differently
from the first; if it isn't, the second will render the same as the first.
When neither register is defined, the class is never established. Thus the
two output lines are identical, as expected.
When either one of the registers is defined, the class should be established:
the two .class lines are identical other than the register name, and both
occur before the .cflags call. So if either "early" or "late" is defined, one
would expect the second output line to differ from the first. But only in the
"late" case does it.
