[PATCH 14/15] environment: drop comment_line_char compatibility macro

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is no longer any code which references the single-byte
comment_line_char. Let's drop it, clearing the way for true multi-byte
entries in comment_line_str.

It's possible there are topics in flight that have added new references
to comment_line_char. But we would prefer to fail compilation (and then
fix it) upon merging with this, rather than have them quietly ignore the
bytes after the first.

I did merge against 'next' and there are no such topics. And likewise
"log -Scomment_line_char next..seen" shows nothing. But as somebody who
maintained a long-running fork for many years, who knows what people are
carrying in their private trees. ;)
