[vim/vim] Multi-line Comment Indenting With C -- incorrect initial spacing (#8118)
cecamp
Describe the bug
Normally, a multi-line comment in C will show a new "*" at the correct indentation every time a carriage return is entered. However, that is not the case with the attached example file. Instead, extra (unwanted) spaces are prepended prior to the asterisk. Removing a line or two from the example file often shows no initial spacing.
(hopefully I've successfully attached cindent-prblm.c and bad.vimrc, because although nominally attached I don't see a confirmation list)
To Reproduce
Detailed steps to reproduce the behavior:
- vim -u bad.vimrc cindent-prblm.c
- Go to bottom of file: G
- Append to bottom of file: o
- You'll see that, instead of beginning with " * ", the line begins with a number of unwanted extra spaces: " * "
- I will note that deleting a line in the comment area above frequently changes the number of unwanted initial spaces, sometimes yielding no initial spaces; ie. "* "
Expected behavior
It should start with " * " (or some number of spaces following the asterisk).
You can see what it should start with by
- vim -u bad.vimrc cindent-prblm.c
- Go to 4th line: 4G
- Append: o
Environment (please complete the following information):

vim --version.)

apparently it didn't. So I'll attach them now on the vimdev mailing
list. Sorry about that...

Looks like "Attach files by ...selecting..." them did not work. Please see the vimdev mailing list for the two files.

Your 'cinoptions' ends in "*30", which means Vim will look back only 30 lines for the start of a comment.
But the comment is 32 lines long. Either remove that restriction, or use a larger number. "*50" works fine.

Closed #8118.

Thank you, Bram! I've been suffering with that problem for years -- and
it was just an option I set up years ago. I've now set that parameter to
200...
