Details:
Commit 2cc968c7 (whose author I've added to this bug's cc list, since he may
not ordinarily monitor this bug tracker) introduced a regression in the -me
macro set.
It can be demonstrated with the command
printf ".nm 1 1\nHi.\n" | groff -a -me
Running this command against the version of tmac/e.tmac-u from before that
commit gives the expected output:
<beginning of page>
1 Hi.
Running it after the commit (including using the latest version of e.tmac-u)
gives:
[...]/tmac/e.tmac:99: backtrace: macro 'nm'
troff: <standard input>:1: warning: number register '_#p' not defined
[...]/tmac/e.tmac:100: backtrace: macro 'nm'
troff: <standard input>:1: warning: number register '_#f' not defined
[...]/tmac/e.tmac:100: backtrace: macro 'nm'
troff: <standard input>:1: warning: bad font number
<beginning of page>
1Hi.
