Subject: Fix copy of line with len = 0
X-Git-Url: https://git.danieliu.xyz/?a=commitdiff_plain;h=5d2d9d540d84761cf11648ea42a6413001a5d7b9;p=st.git

Fix copy of line with len = 0

When a line has no any character linelen is 0, so last = &term.line[y][MIN(lastx, linelen-1)]
generated a pointer to the end of the previous line. The best thing we can do in this case
is to add a newline, because we don't have a glyph to print (and consult its state of
wrapping).
