Allow heading to end with \#

Browse Source 
The problem was in a loop that skipped the optional closing hashes in a
heading like this:

    ### This is an H3 ###

Now it checks to see if a hash is escaped and if it is, treats it as a
rightmost character of the heading text, like this:

    ### This is an H3 #\##   ==>   ### This is an H3 ##

Fixes issue #146.
