Re: [Groff] Allowing user also to check if a line starts with horizontal space

[Dorai Sitaram]

Yes, that would work.  Thus, the user defines a particular macro name to change 
the default effect of space-at-line-start (implicit .br), just like the user 
defines BLM to change the default effect of empty-line (implicit .sp).

--d

You mean a `spaces-at-line-start' macro, similar to the
empty-line-macro?
