+This is the parameter file b990.pro:
+    --noadd-whitespace
+    --continuation-indentation=0
+    --maximum-line-length=7
+    --space-terminal-semicolon
+
+Applying perltidy -pro=b990.pro to the following snippet gave two states
+
+    # State 1
+    print
+    H;
+
+    # State 2
+    print H
+    ;
+
+The tokenizer was alternately parsing 'H' as either possble indirect object, 'Z',
+or indirect object, 'Y'.  Two fixes were tested. The first was to modify
+the tokenizer to recognize a ';' as well as a space as a direct object
+terminator. An alternative fix is to not allowing a break before type 'Y'
+so that the tokenizer kept parsing as type 'Y'.  Both fixes work, but the latter fix
+would change existing formatting by the -extrude option, so the first fix was
+used.  With this fix, the stable state is 'State 1' above.
+
+This update is a generalization of the update L<Fixed blinker related to line break at indirect object>
+of 16 Jan 2021.
+
+This fixes case b990.
