Public bug reported:
Text generated by an end-of-input macro trap (set with .em) can not
extend beyond the current page. That is, if it does the output which
should appear in subsequent pages is lost.
It is unclear why the end-of-input trap is not called with the same
behavior as if the macro were called explicitly by the last line of user
input. For some reason, the end-of-page machinery is not working by
the time the .em trap is sprung, or else there is an inherent limitation
of -all- traps which prevents generating multiple pages.
I will attach a simple demo program. The output should contain 100+
lines, but it stops after 65 lines:
#!/bin/sh
nroff <<'EOF' | cat -s
.de EndOfInput
. nf
. nr Max 100
. nr i 1
. while \\n[i]<=\\n[Max] \{\
. nop Generated line \\n[i]
. nr i \\n[i]+1
. \}
---AFTER genreated lines---
..
.em EndOfInput
Main Text
EOF
