 # Description: View an image or images in a directory in pager
 #
+# Note: While it's very easy to fix this in Bash (sample commented),  with the
+#       current POSIX shell script implementation the unmatched patterns are spewed.
+#       A patch to fix this is highly appreciated.

 # Shell: POSIX compliant
