Hi folks, I'm trying to help out another project (quilt) with some non-portability in one of their man pages. Right now they're embedding raw UTF-8 codepoints into text to use line-drawing characters to depict a file hierarchy. This has the unfortunate consequences you might expect for output formats other than -Tutf8.
Therefore please critique the following PIC. It looks okay but I'm sure
it could be improved in appearance and (especially) general style.
Any improvements you can offer that would facilitate generalize this
into output that might be generated by a tool for turning a (sorted)
list of file specs into a pic diagram would be especially helpful,
because this is not the only man page that tries to draw a file tree,
and a general solution that we could hand to man page writers would be
ideal.
Please don't mind the doubled backslashes; this page undergoes macro
expansion, so each pair of backslashes gets reduces. But the leading
whitespace gets eaten, too, so I didn't paste the post-processed
version.
