The attached screenshot (taken from a `geany -c /tmp/blah` invokation) shows an empty blank space before the beginning of the text line.

This was not present before. I dunno if my distro (void) updated geany recently, but this is my likely candidate for the sudden appearance of that annoying whitespace.
Is there a way to disable it ? Or if this is a case of PEBKAC, please tell me.
