Why does geany use #~ for comments in bash instead of just #?

问题

When I select a block of text in Geany (editing a bash script) and hit Ctrl + E to comment, Geany inserts #~ at the beginning of every line, instead of just #. Why?

回答1:

Geany is adding the ~ after the # to mark these lines as been toggled. Ctrl + E is toggeling the comment in default so

# Original Comment
print ("Hello world")

becomes

#~ # Original Comment
#~ print ("Hello world")

And back again

# Original Comment
print ("Hello world")

Without some special marker it would might be hard to recognize what has been comment and what has been normal code.
