I'm confused by the two tests named in the title.

octothorpe_in_property
The test is defined in CMakeLists.txt (link) like this:

# test octothorpe at end of property value are included in value
new_ec_test(octothorpe_in_property comments.in test11.c
    "^key=value; not comment[ \t\n\r]*$")

The matching editorconfig properties in comments.in (link) is:

# Semicolon at end of value read as part of value
[test11.c]
key=value# not comment

escaped_octothorpe_in_property
The test is defined in CMakeList.txt (link):

# test escaped octothorpes are included in property value
new_ec_test(escaped_octothorpe_in_property comments.in test12.c
    "^key=value ; not comment[ \t\n\r]*$")

The matching editorconfig properties in comments.in (link) is:

# Escaped semicolon in value
[test12.c]
key=value \# not comment

Question: In both tests, the regex in the assertion contains a semicolon, but the value contains a hash sign. Is this a bug or did I get this wrong?
