Minor documentation/comment patch for 21.5

This has been a whoops *forever*. Not strictly a bug (unless somebody decides the underlying problem is a bug). I've always preferred the Athena-style scrollbar bindings for left/right mouse, but under XEmacs right-mouse would always lock the keyboard up (while left-mouse was OK, and in fact would UNlock the keyboard for me). The *underlying* problem is that the comment in lwlib/xlwscrollbar.c says "add these translations", but is missing one translation. There's *already* a <Btn1Up> translation that does Release() - so left-mouse works. As listed, Bnt3Down would do a PageUpOrLeft - but when you release the mouse button, Release() doesn't happen, causing a keyboard wedge. Possible bug: Should there be a <Btn3Up>: Release() in the default_translations table in xlwscrollbar.c (there's already Release() for Btn1Up and Btn2Up)? Patch for the comment attached. Feel free to reject if the consensus is that default_translations[] needs fixing instead... /Valdis Index: lwlib/xlwscrollbar.c =================================================================== RCS file: /pack/xemacscvs/XEmacs/xemacs/lwlib/xlwscrollbar.c,v retrieving revision 1.14 diff -u -r1.14 xlwscrollbar.c --- lwlib/xlwscrollbar.c 2001/04/12 18:21:56 1.14 +++ lwlib/xlwscrollbar.c 2001/12/16 09:50:29 ＠＠ -30,7 +30,8 ＠＠ * * Emacs*XlwScrollBar.translations: #override \n\ * <Btn1Down>: PageDownOrRight() \n\ - * <Btn3Down>: PageUpOrLeft() + * <Btn3Down>: PageUpOrLeft() \n\ + * <Btn3Up>: Release() * */
