Subject: bug#15004: 24.3; fill-paragraph on perl-mode indented comment at start of buffer
Date: Fri, 02 Aug 2013 09:43:04 +1000 [thread overview]
Message-ID: <87wqo5vuyf.fsf@blah.blah> (raw)
Starting from emacs -Q,
(progn
(switch-to-buffer "xx")
(erase-buffer)
(insert " # aa aa\n")
(insert " # bb bb\n")
(insert " # cc cc\n")
(insert " # dd dd\n")
(goto-char (point-min))
(perl-mode)
(fill-paragraph nil))
gives
# aa aa
# bb bb cc cc dd dd
whereas I hoped the fill-paragraph would include the first line too,
# aa aa bb bb cc cc dd dd
The problem is only if the lines are at the start of the buffer.
I noticed this under filladapt which narrows to its desired target
region and fills that. The problem occurs both at actual start of
buffer and when narrowed.
I couldn't tell where it might go wrong except that it might be related
to perl-mode using comment-start-skip "\\(^\\|\\s-\\);?#+ *" which has a
\\(\\) group to demand preceding whitespace if not at start of line.
If you change it to
(set (make-local-variable 'comment-start-skip) ";?#+[ \t]*")
then the fill correctly includes the first line.
