withyou that it is at least a strange syntax. It is like this at least since 2009 (commit ba748f7a11e). I'm not sure
parse_bool*is the right place to fix it because it could break code. IMHO the problem is that parse_one_reloption() is
usingthe value provided by user; it should test those (abbreviation) conditions and store "true" (for example) as bool
value.

I don't think we should touch this. If the user chose to write the value
in a specific way, they might've had a reason for that. There's little
reason for us to override it, certainly not enough to justify introducing
a lot of new mechanism just to do that.
