LexVB Folding inconsistency

[pryrt]

Folding is different depending on whether the line after a sub is properly indented, whether there's a blank line, or whether it's improperly indented.

(screenshots from SciTE 5.5.5 with fold.symbols=3 to make folding more obvious)

Properly Indented (folds correctly):

Sub NameHere()
    Set HelpBookP = 5
    Set HelpBookQ = 5

    if a=b then
        Set HelpBookQ = 9
    end if
    Range("K1:K5")
End Sub

Blank line between (fold symbols not showing, but does fold if you click the missing boxed-+):

Sub NameHere()

    Set HelpBookP = 5
    Set HelpBookQ = 5

    if a=b then
        Set HelpBookQ = 9
    end if
    Range("K1:K5")
End Sub

=>

Bad indentation (start-of-fold moves to the unindented Set instead of starting at the Sub where it belongs)

Sub NameHere()
Set HelpBookP = 5
    Set HelpBookQ = 5

    if a=b then
        Set HelpBookQ = 9
    end if
    Range("K1:K5")
End Sub

Visual Basic does not apply meaning to leading/trailing whitespace (unlike Python), so the way it's folded should not be dependent on whitespace. But this experiment strongly implies that LexVB is considering whitespace when deciding on where/how to fold.

(this bug report comes from this Notepad++ Community discussion)

LexVB implements folding based purely on indentation.

A better implementation would be based on keywords.
