is an alias for `c-indent-new-comment-line
' in `
(c-comment-line-break-function &optional SOFT ALLOW-AUTO-FILL
This function is obsolete since 21.1;
use `c-indent-new-comment-line' instead.
Break line at point and indent, continuing comment or macro if within one.
If inside a comment and `comment-multi-line' is non-nil, the
indentation and line prefix are preserved (see the
`c-comment-prefix-regexp' and `c-block-comment-prefix' variables for
details). If inside a single line comment and `comment-multi-line' is
nil, a new comment of the same type is started on the next line and
indented as appropriate for comments. If inside a macro, a line
continuation backslash is inserted and aligned as appropriate, and the
new line is indented according to `c-syntactic-indentation'.
If a fill prefix is specified, it overrides all the above.
