    _______________________________________________________

Details:

It is useful to have comments in scripts parsed by the rescue parser, even
though it is only for limited use cases and it's trivial to add the comment
parsing capability.  Even though comment are currently treated as unknown
commands and thus harmless.  Errors are output which confuse (see this issue
<https://savannah.gnu.org/bugs/?func=detailitem&item_id=50963>) and are not
aesthetically pleasing.

I've attached a patch that adds this feature by only changing one line.  I
hope this patch will be accepted, but if not at least it might be useful to
others search on this issue.
