OK, there's more to this than just the quoting. I fixed the quoting,
but I still see error messages, like this one:
groff -t -man man\man1\chem.1 > man\cat1\chem.1
<standard input>:4: name expected (got a node): treated as missing
<standard input>:0: warning: numeric expression expected (got `a')
<standard input>:550: name expected (got a node): treated as missing
<standard input>:410: warning: numeric expression expected (got `a')
These come from the .lf directives, like this one:
.lf 1 man\man1\chem.1
One possible solution to this is to convert all backslashes to forward
slashes '/' when writing the .lf directive. Unfortunately, there are
quite a few places where .lf is emitted, so before I go ahead and do
it, I have a question: why do the programs that read those .lf
directives choke on such file names? The Groff manual clearly says
that the format of the .lf directive is
.lf line [filename]
So the programs who read this ought to interpret what follows the line
number as a file name. Why do they try to interpret that as something
else, like node or whatever? What am I missing here?
TIA
