> 2. Open an empty buffer in a mode like conf-mode.  Enable abbrev-mode.
> 3. Type "# this is a comment", select the line, and run M-x
>    add-mode-abbrev, give it some abbrev like "tc".
> 4. On a new line, type tc and then M-x reindent-then-newline-and-indent
>
> I expect this to insert "# this is a comment", but instead it inserts
> "#this is a comment".  Note the missing space between the
> comment-start marker and the comment text.

> For context, this came up in a major mode (ledger-mode) where I had
> bound RET to reindent-then-newline-and-indent, so it happens quite
> freqently to me.

> I think just making reindent-then-newline-and-indent use a marker for
