Ignore a comment (<!-- ... -->)

[trustin]

Hi! 👋 Thanks a lot for the great plugin. In some of my .md files, the first heading has a comment, e.g.

# This is the title <!-- .slide: style=... -->
...

The plugin will rename the file into This is the title <!-- .... -->.md, which is probably not what people wanted.

What do you think about ignoring/removing the comment block from the heading automatically when determining the file name?
