Package: screen Version: 5.0.1-2 Severity: normal X-Debbugs-Cc: [email protected]
Hello, The %= string escape can be used to align or force the position of some string. For instance caption always "X%010=Y" would show a caption string "X Y" on the bottom of the terminal. What it actually shows for me is "X 8Y". The 'Y' is one character too far and the '8' is likely a stray character in the buffer. (My regular caption string has an 8 in that position.) But sometimes, the Y is entierly missing. Especially when the %= wouldn't truncate the existing string, but rather pad it. I guess sometimes the 'Y' doesn't show up at all because there's a stray NUL byte at the position the Y is supposed to go. This bug really looks like an off-by-one error when indexing the buffer that builds the caption string.
