@ -92,6 +92,11 @@ CVS code -
the paragraph search left us on the magicline, so as to avoid
a segfault. (DLR)
- winio.c:
titlebar()
- Rename some variables for consistency, properly handle the
case where the prefix length plus the path length is greater
than the amount of space available, and fix a typo in an
assert(). (DLR)
unget_kbinput()
- Remove the wide character handling, as it didn't work properly
with respect to function keys. (DLR)
