This is Renzo's code.
Debian's lintian returns the following warning: acute-accent-in-manual-page
This manual page uses the ' groff sequence. Usually, the intent to generate an apostrophe, but that sequence actually renders as a an acute accent.
For an apostrophe or a single closing quote, use plain '. For single opening quote, i.e. a straight downward line ' like the one used in shell commands, use \(aq.
The situation is even worse when there are code blocks, mainly code chunks or commands. E.g., copy-paste fails.
Type the following command echo 'Hello World'
.
$ echo 'hello world'
The following code cannot be compiled:
int main() {
int example = 42;
switch (example) {
case 'a': return 10;
default: return 42;
}
}
