[Groff] Groff pipeline plumbing problem

[Rick Richardson]

It looks to me like the "groff" driver in the latest CVS version is
putting together bogus pipelines.  This is with the latest CVS version:

$ /usr/local/test/bin/groff -P-Ixxx.1 -P-o0 -P-i100 -t -man -Thtml xxx.1
post-grohtml:<standard input>:1:fatal error: the first command must be `x T'

It appears to me that post-grohtml is getting exec'ed *twice* by
"groff", and the second time there is already HTML in its input!!!!!

Here is the evidence from strace -f ....

$ grep bin/post-grohtml strace.out
22511 execve("/usr/local/test/bin/post-grohtml", ["post-grohtml", 
"-Ilinuxtrade.1", "-o0", "-i100"], [/* 38 vars */]) = 0
22594 execve("/usr/local/test/bin/post-grohtml", ["post-grohtml"], [/* 38 vars 
*/] <unfinished ...>


Operator error, or bug?
