commit 21cc9d13f34d116b521c4415098ca1c9993bd198 Author: Nick Mathewson <nickm@torproject.org> Date: Wed Sep 25 21:13:30 2019 -0400 annotate_ifdef_directives: clarify situation with newlines Our line limit is 80 characters, assuming that there is a single terminating newline character that counts towards the limit. On Windows, this might go as high as 81 characters, if we count CRLF as two characters. --- scripts/maint/annotate_ifdef_directives | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/scripts/maint/annotate_ifdef_directives b/scripts/maint/annotate_ifdef_directives index 4463d8382..b6bb147ce 100755 --- a/scripts/maint/annotate_ifdef_directives +++ b/scripts/maint/annotate_ifdef_directives @@ -26,7 +26,10 @@ import re # Any block with fewer than this many lines does not need annotations.
