In b2afce5c79, the db filename is
wrapped in double-quotes when passing it to the sqlite3 tool's
`.clone` helper command.
For parsing safety, we avoid performing this cleanup if the filename
itself has a double-quote character in it. Otherwise, a malformed
filename could lead to arbitrary injection into the sqlite3 command.
In be24680046, the sqlite3 wrapping
changes to single-quotes. Either the safety check should be amended
to block pathnames with single-quotes, or the sqlite3 wrapping should
revert to double-quotes.
I opted for the latter here because i think single-quotes are more
likely than double-quotes to show up in pathnames (e.g. a folder named
"Daniel's files"), but either change would be fine, of course.
