bug#10855: 24.0.93; hideshow does not hide comment with cursor in first line's indentation

[John Yates]

hs-show-block will reveal a collapsed comment block when the cursor is
in that block's indentation.  hs-hide-block will collapse a comment
block when the cursor is in the indentation of any line other than the
first.  hs-hide-block will _not_ collapse a comment block if the
cursor is within the _first_ line's indentation.

The following one line patch corrects this slight asymetry:
